When installing FlexSim, has the installer ever quit, saying "Installation Cancelled" or "FlexSim must close"?     Installation Canceled Installation was cancelled by user.   Or has your FlexSim installation ever had errors upon starting the software?     FlexSim has encountered a problem. Your work is saved in recovery files. Please notify FlexSim Technical Support. Retrieve your recovery files, then email FlexSim. Do you want to restart?     FlexSim encountered an unrecoverable error and must close. Please notify FlexSim Technical Support about this issue.   This can be frustrating any time, let alone for a brand new FlexSim installation.   Here are some possible solutions that may help FlexSim install or start properly:   1. Meet the System Requirements   Make sure that your computer meets FlexSim's minimum system requirements. If your computer's hardware or operating system is out of spec, you may not be able to install FlexSim, or it may not start or work properly.   Don't overlook the disk space requirement. You'll need about 2.5 GB free for the installer and the completed installation in order to install FlexSim. Low disk space will cause the installation to fail.   Graphics specifications are particularly important, as incompatible/nonexistent graphics hardware or out of date graphics drivers may cause strange graphics behavior or other issues. See this article for more graphics considerations, tips, and guidance for installing or upgrading graphics drivers.   2. Windows Updates, Driver Updates   FlexSim relies on some newer Windows components and libraries provided by Microsoft in patches and updates. Make sure your computer is up to date with all Windows updates.   In addition to Windows updates, be sure to upgrade your system's graphics drivers, as FlexSim relies on fixes and features found in the latest graphics drivers from NVIDIA, Intel, or AMD. It is not enough to just use Windows Update to check for new graphics drivers - you should check the websites for your system manufacturer or graphics vendor specifically for updated graphics drivers. See our graphics article for more detailed information.   3. Reboot your computer   Windows has improved enormously over the years, but even with modern Windows sometimes a good, old-fashioned reboot can do the trick, especially if you have recently installed or uninstalled other software or Windows updates.   4. Run as Administrator   Software Installation: Ensure that you have the proper privileges on your PC to install new software.   Install FlexSim by right-clicking the installer file and choosing Run As Administrator. If you don't have admin rights, you will be prompted to enter credentials with admin rights. Enter the proper credentials to allow the software installation to proceed.     Startup Issues: Try starting FlexSim with higher permissions by right-clicking the program icon and choosing Run As Administrator. If you don't have admin rights, you will be prompted to enter credentials with admin rights. Enter the proper credentials and the software should start with elevated permissions. Does this solve the problem?   Some users have reported that some FlexSim components are blocked by default, but can run properly when FlexSim is started with elevated privileges.   If you find this is the case for you, work with your IT group to determine how to unblock the DLLs or other components required by FlexSim.   5. Delete FlexSim's saved settings   Sometimes when FlexSim has trouble starting up, it can be due to a corrupted prefs.t file. FlexSim's prefs.t file stores your FlexSim settings and preferences and is located at:   %APPDATA%\Flexsim\FlexSim <version>   The %APPDATA% address is a shortcut to your Windows user account's Roaming directory. This animation shows how to get to your %APPDATA% directory:     With FlexSim closed, delete this prefs.t file. Then try starting FlexSim. Are the problems resolved?   6. Reinstall FlexSim   Completely uninstall FlexSim and try a new installation. It may be worth downloading a new copy of the full installer to ensure there was no corruption in the install package.   You could also try the .msi installer, instead of the .exe. When installing using the .msi you can save a log of the install process. This could help with debugging if there are still problems.   Whichever method you use when reinstalling FlexSim, be sure to right-click the installer and choose to Run as Administrator (see the Run as Administrator section above).   7. Update your computer's .NET installation   FlexSim relies on Microsoft's .NET Framework for some functionality. Windows 10 includes a compatible .NET version, or if a compatible version is missing the FlexSim installer will try to download and install .NET directly from Microsoft. If your computer/network does not allow this you may need to update .NET yourself. Click here to download the .NET framework directly from Microsoft.   After installing the .NET Framework, please revisit the Windows Updates section above. Microsoft may provide new security fixes that should be applied to your .NET installation.   8. Reinstall Microsoft Visual C++ Redistributable   These are run-time components provided by Microsoft that are required to run FlexSim. Normally these components are installed during FlexSim's installation process. If FlexSim is encountering errors, it could be caused by a broken or out of date C++ redistributable. Click here to download the latest Visual C++ Redistributable directly from Microsoft.   After reinstalling the Visual C++ Redistributable, please revisit the Windows Updates section above. There may be new security fixes for the redistributable.   9. Antivirus   We have seen instances where FlexSim is blocked by an overzealous Antivirus software. If FlexSim doesn't start up at all, despite a new installation, this could be the case.   To test this, temporarily disable your antivirus and try to install or start FlexSim. If the problem clears up then your antivirus may indeed be blocking FlexSim. In this case, work with your IT department to configure the appropriate settings to allow FlexSim to run alongside your antivirus solution.   Remember to re-enable your antivirus software after this test.   10. Windows Event Viewer   If FlexSim still won't install or start, try checking the Windows Event Viewer to see if there are any errors related to installing or starting FlexSim. If so, please send those our way so that we can troubleshoot further. In case you've never used it before, here is a tutorial covering the Event Viewer.   Add your comments below on what did or didn't work for you, other problems or symptoms you encountered, or tips and tricks that helped you solve them.   Fixes for older versions   The following suggestions apply to outdated versions of FlexSim.   Update OpenSSL DLLs   Applies to FlexSim versions 7.0.0-20.2.0 (excluding LTS versions 20.0.9+) Some older FlexSim installations may crash shortly after FlexSim opens, when FlexSim's start page contacts our remote servers for dynamic content, due to a new system incompatibility with the openssl library that shipped with these older FlexSim versions.   Newer versions of FlexSim include updated files that resolve this problem. Install the latest version of FlexSim to obtain updated versions of the following two files:   C:\Program Files\FlexSim <version>\modules\Emulation\openssl\libeay32.dll C:\Program Files\FlexSim <version>\modules\Emulation\openssl\ssleay32.dll   Copy those updated DLLs to your affected FlexSim installation, under its program\Webkit folder, overwriting the older version of those files.   Alternate workaround: disconnect your computer from the Internet, both wired networks and Wi-Fi. Start FlexSim. Go to File > Global Preferences > Dynamic Content tab. Deactivate all of the options there. You can now reconnect to the Internet and FlexSim may work properly the next time you start the application.   Uninstall KB4571756   Applies to FlexSim versions 7.7.0-16.2.2   A Windows 10 patch released in September 2020 may prevent FlexSim versions 7.7.0-16.2.2 from starting.   If you are using one of these older versions of FlexSim and the program will not start, try removing this Windows update: https://support.microsoft.com/en-us/help/4571756/windows-10-update-kb4571756  

Recommended System Requirements   This article complements FlexSim's System Requirements. We'll go over each of the major components, discuss their importance to a FlexSim model, and make recommendations to help you decide on the right hardware for your situation.   CPU   Single Model Run   A single run of a FlexSim model (ie not an experiment or optimization run) is single threaded, which means it runs on only 1 CPU core. Buying a processor with more cores won't speed up a single simulation run. To complete single model runs more quickly, use instead a processor with a faster single core clock speed (gigahertz, or cycles per second) or better efficiency (instructions per cycle).   In short, for the fastest individual model runs, you want the fastest processor possible, regardless of the number of cores.   Experimenter or Optimizer - Multiple Simultaneous Replications   When you're doing multiple simultaneous model runs using the Experimenter or Optimizer, FlexSim takes advantage of multiple CPU cores to run simulation replications in parallel.   By default, FlexSim spawns as many replications as you have cores; for example, a Quad core processor enables four single-threaded simulation runs to process simultaneously, one on each core, getting you results four times faster than by using a single core processor at the same speed/efficiency.   If necessary, you can manually limit the number of concurrent replications by setting the Max Cores value from FlexSim's Main Menu under Statistics > Experimenter > Advanced tab > Max Cores input field. Each replication consumes some amount of system RAM, so if you run out of RAM before you run out of cores, it may be necessary to limit the number of cores used to run replications.   Conclusion   If you’re primarily doing single simulation runs, choose a faster processor speed regardless of the number of cores. If you’re primarily doing experiments, choose a processor with a high number of processing cores (and make sure your system has enough RAM to support them - see the Memory heading, below). If you’ll be doing both, choose a processor that strikes a good balance between core speed and core count.   Memory   Considerations   Random Access Memory, or RAM, is a PC's fast "working" memory, where it stores the data and programs it is currently running (don't confuse this with your much slower hard drive, where data is stored "at rest"). Most consumer Windows computers top out at 32 or 64 GB of RAM, though Windows is capable of supporting much more when coupled with high-end hardware (see limits per OS here).   Your computer is always doing many other things besides just running FlexSim. Your operating system itself has memory needs for all the processes it is constantly running. You probably have an antivirus solution, maybe a backup software, and often other utilities running invisibly in the background. Then there are all the applications you currently have open - your email, a web browser, music streaming, etc. All of these are consuming RAM.   As you plan your FlexSim hardware, be aware that you should have enough RAM to run all these other applications, plus your FlexSim model, plus have a good amount of extra RAM as a buffer.   FlexSim's Requirements   Many FlexSim models will use less than 4 GB of RAM in a single model run, but it all depends on your simulation and data. Some large and complex models can and do go above 4 GB of RAM utilization (sometimes well above). If FlexSim's RAM utilization starts approaching a high percentage of your total available system RAM, your computer will turn sluggish or totally unresponsive as it runs out of memory and begins paging out to disk for its memory needs (which is orders of magnitude slower than RAM).   A FlexSim system should have 16 GB of RAM as a minimum. For the best experience we recommend 32 GB of RAM or more. Many modern consumer PCs meet this recommendation. See FlexSim's latest minimum and recommended system requirements here.   Experiments and Optimizations   Experiments and optimizations run several replications of your model simultaneously, so make sure you have enough total memory in your system so that each replication can hit its peak memory needs, while still leaving enough memory for the system and other running applications (OS, antivirus, other background processes, etc.).   In addition, the experimenter saves statistics data for each replication by default. Each completed replication will send its statistics collectors' data to the main FlexSim thread, where it will ultimately be stored in the results database file on the hard drive. However, several stages of the transfer process require two copies of the data. In addition, all child processes can transfer data simultaneously. So, if you have a model that generates 100MB of statistics data, and you run an experiment with 8 CPUs, and all 8 CPUs finish a replication at roughly the same time, you'll need at least 1600MB (100 MB x 2 x 8) to transfer the data successfully, on top of all the other RAM utilization.   Example Scenario   I've developed a simulation model and now I'd like to run multiple replications using the Experimenter. Watching my simulation run normally, while monitoring FlexSim's memory usage with Windows Task Manager, I see that over the entire course of its run my simulation peaks at about 2.1 GB of RAM at its highest utilization. My computer system has 16 GB of RAM. When FlexSim is not running at all, the system uses about 20% of its resources for the operating system and other background processes. This leaves about 12.8 GB of RAM free. How many concurrent replications of FlexSim can my PC support? 12.8 GB / 2.1 GB per replication = 6.1 concurrent replications So, I might get by with allowing 6 concurrent replications of FlexSim, but I feel like 5 is a safer bet to give the system a bit of headroom, and because running the experimenter and collecting results data also requires some additional memory overhead. Since my computer has a quad-core processor and uses simultaneous multithreading (SMT) (which allows each core to run two FlexSim replications at once), FlexSim's default would be to run 8 concurrent replications. My calculations showed that 8 concurrent replications would be too many, and will probably bog down my PC, slowing or halting the entire process. I will limit the number of concurrent replications the experimenter will use by setting the Max Cores value to 5. This option is set from FlexSim's Main Menu under Statistics > Experimenter > Advanced tab > Max Cores input field.   Your settings will differ from this example. Check your computer's amount of RAM, the peak memory needs of your simulation models, and your baseline RAM utilization when you're not running any simulations. Factor in a reasonable % as a buffer. Use these values to determine how many concurrent FlexSim replications your computer may support.   When allowing FlexSim to use its default of running the max number of replications your CPU supports, please keep in mind that many multi-core CPUs actually run multiple threads simultaneously per core (simultaneous multithreading - SMT). To fully take advantage of all the simultaneous replications that your PC could run at once, be sure to get enough RAM for all the replications your CPU is capable of. For example, a 4-core CPU with support for SMT could run 8 simulation replications at once. Make sure you have the memory to do so! If not, be sure to use the Max Cores option to limit the number of concurrent replications.   Conclusion   A system meeting FlexSim's minimum RAM requirement will have enough memory for a single model run of most simulation models. If your simulations are large or complex, or if you intend on running experiments or using the optimizer, you should meet the higher recommended spec of 32 GB of RAM or more.   Disk   Space Requirements   The FlexSim installer may be up to 1.2GB in size, depending on the FlexSim version.   After installation, FlexSim's program files use up to 1.2GB of disk space. Your model files, CAD layouts, images, custom 3D shapes, import data, exported reports, and other simulation related assets that you provide will take disk space in addition to the software's installed footprint.   Disk Speed   Most FlexSim models will run from memory, so hard drive speed isn't really an issue. However, if you're reading/writing with files/databases while the model is running, disk speed could make a huge difference; a Solid-State Drive (SSD) is a must in that case. Alternatively, try to do data reading and writing before and after the simulation run, if possible.   FlexSim recommends SSDs in general because they make every interaction with your computer feel faster and more responsive. You won't regret an upgrade from a regular, spinning hard drive to an SSD.   Conclusion   Consider upgrading your hard drive to an SSD if you will be reading or writing to files or databases during a model run, or to generally improve system responsiveness. Graphics   Recommended Graphics   The better/newer/bigger/faster the graphics processor, the better the performance. Integrated graphics, where a smaller GPU is packaged into the CPU, have gotten much better in recent years, but a discrete GPU remains the most powerful graphics solution.   FlexSim works best on Nvidia GeForce RTX GPUs, but Nvidia Quadro and AMD Radeon are also good solutions. Most recent integrated graphics solutions meet FlexSim's minimum graphics requirements, but in general will not perform as well as discrete graphics.   Graphics Driver Updates   It is also important to note that you should keep your graphics drivers updated to the latest version. If your graphics hardware meets FlexSim's minimum requirements but you are experiencing graphical issues in FlexSim, a graphics driver update may solve the problem. Please check out this article for some common symptoms and solutions to graphics issues within FlexSim.   Virtual Reality   FlexSim supports Oculus Rift/Meta Quest 2, HTC Vive, and Windows mixed reality virtual reality platforms (see demo models). Be sure to meet FlexSim's higher recommended specifications if you plan to use VR.   Conclusion   While recent integrated graphics solutions meet FlexSim's minimum requirements, a discrete graphics solution is a better choice. For maximum performance, FlexSim recommends a recent NVIDIA GeForce RTX GPU.

This small model shows how to batch various parts together to form 'valid' combinations as they become available. This differs from a regular combiner where the component quantities are set in advance of the components being accepted in the combiner (often based on the type of item on port 1 entry). The valid combinations are shown as the quantities required for a number of products in a global table "ProductPartQuantitiesGrid": By referencing the first picture and this table, you may be able to see that the model first constructs 4x Product2 followed by one product1 and a Product3. In the background process we are creating a token for each product which is then trying to pull all the parts needed while competing with the other products. This part of the process could be constrained in some way, for example where there is a target for the number of each product to produce over a time period. So these tokens are being created in the Object Process Flow of the object we're calling OpportunityCombiner at time zero based on the table shown above: Instead of the normal array generation this model creates a table label of the required parts for a product and stores it on the token. For Product1 that looks like this: Tables aren't quite fully supported as labels yet so the syntax is a little odd when using them - in this case we do it like this: Table(token.partsTable)[1]["Part"]  // evaluates to 'F' Setting the labels up so that syntax works is a bit more complex. Note that the partsTable label is actually a pointer to the data table label on the token - called partsTableData. To get the view shown above you need to right click on the label partsTabelData and select "Explore As Table". Hopefully in the future this may be more streamlined if more people start using labels as tables. The grid table doesn't play nice with sql, so another table creates itself at reset with a structure that is sql friendly: That means the label table can be created with this query: SELECT Part,Quantity FROM ProductPartQuantities WHERE Product=$1.product What remains for the product token just involves getting the parts (a subflow) and them moving the array of all items to the combiner (a queue in the example); stacking them together and releasing to the conveyor before looping back to try and produce another. Below you see the main flow with four tokens - one for each product defined in the grid. The subflow to get parts reads the token's table of parts for its product, and tries to get the correct quantities for each. This is similar to @Jordan Johnson 's solution for pulling from multiple lists, but is instead considering the table of parts from one list rather than arrays of resource lists and quantities. The key aspects of this flow are that 1. the first loop in the check section leaves the parts on the list, while the 'commit' section removes them 2. we exit the check loop by using the pull timeout when we fail to pull the required quantity of a part type 3. those that fail listen for pushes to the parts list 4. success full product pulls insert the items pulled to the tokens label 'allItems' for later use. Attached is the model. It should be relatively simple to transfer the process and tables to another model. OpportunisticCombiner.fsm

FlexSim 2017 Update 1 is available. If you have bug reports or other feedback on the software, please email [email protected] or create a new idea in the Development space. Release Notes Changed FlexSim to store strings using UTF-8 encoding. Added support for Oculus Touch controllers. Implemented OpenVR for HTC Vive compatibility. Improved the shadow frustum calculation in VR so that shadows look better. Added a global preference for changing the resolution of the shadow map. Added support for nested queries in SQL. Added ROW_NUMBER as a SQL keyword. Implemented F2 and Esc functionality in tables. Updated the table view and labels tab to be more robust with different datatypes. Added Table(name) method for referencing Global Tables. Added more FlexScript classes, including List, AGV, Conveyor, and TrackedVariable. Added more properties and methods to existing FlexScript classes, including Object stats and additional string methods. Improved scientific notation for literals in FlexScript. Added a start value to tracked variables. All tracked variables in the model now reset on model reset. Changed itemtype references to referencing an item's type label instead. Improved the Person flowitem's 3D shape. Added repeating events to time tables. Added a short description field to user commands. Made the gantt charts and time charts scroll with a fixed time window. Removed the global table Clear on Reset checkbox and replaced it with a reset trigger. Added new visualization options for the Rack. Added duplicate buttons to the Excel Interface window. Added a duplicate option to the Toolbox's context menu. Taskbar now shows experimenter/optimizer status and runtime based upon stop time. Disabled deleting objects while the model is running. Fixed an issue with the undo history when pasting over nodes with pointer data. Fixed issues with using the ternary operator after properties. Fixed an issue with writing to Access databases with read-only fields. Included fixes listed in 17.0.4. Backwards Compatibility Note: the following changes may slightly change the way updated models behave. Removed the FlexSim WebServer application from the default installation and developed a new WebServer application using Node.js that streams the 3D view much faster. The new WebServer can be downloaded through FlexSim's Online Content. Existing models will continue to work with itemtype, but new models should be built using a type label instead of the itemtype attribute and commands. Process Flow Added an Assign Released Resource(s) To field on the Release Resource activity. Added functionality to allow you to Ctrl+Drag activities in an activity block. Added a right-click menu option and Alt+Click to open the Token View. Added a sampler to the assign labels Label Name field so you can sample other activities or tokens to get label names. Added a right-click menu option to open multiple views of a Process Flow. Added an Assign To property to the Create Tokens activity. Added a Make Array label aggregation type to the Batch. Added Center in View buttons for fields with pointer data. Added a name property to the Token FlexScript class. Fixed a bug with duplicating Process Flows using the Toolbox. Backwards Compatibility Note: the following changes may slightly change the way updated models behave. Updated the Pull From List activity so it does not assign a null label when nothing was pulled or the token was released early (manually). Previously, if you used a Max Wait Timer or Max Idle Timer (or some other mechanism) to release a token from a Pull from List prematurely, the label specified in the Assign To field would be created with a value of NULL. Now, the label will not be created. This may break other models that are checking to see if the label value exists. For example, saying objectexists(token.pulled) will throw an exception if the pulled label is never created. This can be easily remedied by changing the code to objectexists(token.pulled?). The ? will cause the value returned to be nullvar when the pulled label does not exist. Universal Edit fields are now more strict when accessing labels on a token. Previously, typing token.labelThatDoesNotExist would happily return NULL and move on. Now the Universal Edit will throw an exception if the label doesn't exist. This does not include Universal Edit fields that assert labels, for example the Assign To fields.

FlexSim 2016 Update 1 Beta is available. Download FlexSim 2016 Update 1 Beta (updated 17 June 2016) If you have bug reports or other feedback on the software, please email [email protected] or create a new idea in the Development space. Release Notes FlexSim 16.1.0 Added group commands (groupaddmember(), groupmember(), groupnummembers(), groupremovemember()). Global Lists will now update their Initial Content on reset when connected to a Group if the group's members change. Added support for the UPDATE clause in SQL. Added support for the RAND expression in SQL (uses stream 0 and will always be the same for a given query/row selection combo). Improvements to speed and memory usage when performing SQL inner joins. Tracked variables with type Categorical can now store arbitrary states. Added a Kinetic Level tracked variable type (e.g. Battery Level). You can now hold down the Alt key while clicking and dragging in the 3D view to ignore all objects. You can now resize objects while maintain their aspect ratio by pressing both the left and right mouse buttons down on a sizer arrow. Updated dashboard charts to support x-axis scaling. Added OnStop and OnResume events to 3D objects for use with event listening objects (Wait for Event and Event-Triggered Source in Process Flow). Video Recorder can now record Dashboards. Time Tables, MTBF/MTTR and User Events can now be disabled. Experiment variables can be set to enable/disable these objects. Fixed an issue with the VideoRecorder not loading properly. Fixed issues with windows and popups not opening on the correct monitor when using a multiple monitor setup. Fixed Fluid Conveyor throwing exceptions on reset. Backwards Compatibility Note: the following changes may slightly change the way updated models behave. Updated to OpenGL 3.1. Deprecated OpenGL functions, such as glBegin(), glEnd(), glVertex(), glNormal(), and glTexCoord(), may no longer work correctly on some graphics cards. You should instead use the mesh api. Changed the way that fixed resources (except the Combiner) receive items when they are being transported in. Previously, when they were notified that an item was being transported in, they would close their inputs and create an event to receive the next item. This would cause problems if the upstream objects had multiple items to send because their routing strategy would work differently when transporting vs not transporting. We have fixed this so that routing strategies will work the same when transporting as when not transporting. This may change the way that old models work because it changes the events that are created, and, obviously, it fixes routing strategy logic. menumain(), menubelow() and getviewmenu() have changed. Instead of returning a double, they now return a var. Any calls to these commands will need to be updated to use var or the value returned will be 0. double myMenu = getviewmenu(); Changes to: var myMenu = getviewmenu(); Conveyor Added Ports to the Entry and Exit Transfers. Added a Restart Delay setting to Conveyor Types. Fixed the Join Conveyors Tool when connecting conveyors with a custom conveyor type. Various bug fixes and improvements specifically with regards to items moving between conveyors and transfers. Backwards Compatibility Note: the following changes may slightly change the way updated models behave. Changed the way stopping a non-accumulating conveyor works when propogating stops to straddled conveyors. When a conveyor is stopped, it will act the same as if an item on the conveyor were stopped. Process Flow Added Preemption activities (Save Token Context, Release Token and Restore Token Context). Added gettokens() and getbatch() commands. Added Templates for Fixed Resource and Task Executer Process Flows. Added a Token Data to Preserve option to the Sink and Finish activities. In the Tokens window you can view Dead tokens and explore their data. Token Trace History is now stored as a label on the token. Added a Speed Type and Repeat Type to the Run Animation activity. A lot of improvements to the Zone. Updated the evaluation of the Return Value from the Finish activity so that executesubflow() can get a return value from multiple Finish activities. Added Activity Profiles to the token trace histories. Fixed a bug causing the Wait for Event to evaluate its Max Wait Timer even if the token left the activity. Fixed issues with the releasetoken(), createtoken(), and releasebatch() commands working differently when running vs stepping. Backwards Compatibility Note: the following changes may slightly change the way updated models behave. Changed the way that a token manually released (preempted) from waiting in a task sequence activity manages the task that it's waiting on. Now the task will be removed, and the task executer preempted if currently working on it. This may change older models that release tokens in task sequence activities. AGV Added Event info to AGVs and Control Points for use with event listening objects (Wait for Event and Event-Triggered Source in Process Flow). Added AGV templates to Process Flow. Fixed bug with way points not firing their OnArrival for redirected AGVs. Fixed issue with arrival waypoints not firing correctly with non-zero end speed travel tasks. Backwards Compatibility Note: the following changes may slightly change the way updated models behave. Fixed the order by which AGV trailers are attached to their AGV. This will affect old model trailer ordering.

The following article applies to FlexSim versions 26.0 and older. For Autodesk FlexSim 2027 and onward, please visit Autodesk FlexSim 27.0 Licensing and Sign-in Experience   Names and version numbers   FlexSim releases have names like “FlexSim 2016 Update 1” (also known as FlexSim 16.1), with corresponding version numbers in the format year.update.bugfix.   The year version number tracks with the “release year” when the software was released. For example, FlexSim 2016, having version number 16.0.0, was released for the 2016 “release year”. A “release year” roughly follows the calendar year, but a 2017 release could come at the end of the 2016 calendar year, for instance. The update version number is a count of how many feature-updates have been produced for a “release year”. For example, version 16.0.0 is the first feature-release for 2016. It is not an update, so the update version number is “0”. FlexSim 2016 Update 1 has version number 16.1.0 – it is the first update to the 2016 release. 16.2.0 is the 2nd update, and so on. Bugfix version numbers change when software is released without significant new features, but where errors, inconsistencies, or other bugs are fixed. For example, the first bugfix release for FlexSim 2016 Update 1 is 16.1.1, the next 16.1.2, and so on. Release schedule   New versions of FlexSim are released on a loose schedule:   Yearly release: November beta, December release. Update 1: March beta, April release. Update 2: July beta, August release. Bugfixes: as needed As with all future-looking plans, this schedule is subject to change. You should not rely on this schedule for making purchasing decisions.   How licensing works for a given version number   A new license is required for feature releases (i.e. year and update releases). Bugfix releases do not need a new license. For example, if you have a 16.1 license, you can license any FlexSim 2016 Update 1 releases, including all its bugfix releases, like 16.1.0, 16.1.1, 16.1.2, etc.   Licenses can also be used for older versions – i.e. they are backward compatible. For instance, if you have a 16.1 license, it can license any 16.1.x release, plus all older versions of the software back to 5.0.0. However, your 16.1 license will not work for any newer versions, such as 16.2.x or 17.0.x.   License Codes   Your license code should look something like mycompany.com03-A9B8C-7D6E5-F4G3H-FSENT17.1. Each part conveys some information:   mycompany.com- means this seat was initially licensed to mycompany. 03 is a unique index number for the license, but the actual number is meaningless. This number persists across upgrades. The mycompany.com03 license, if upgraded to version 18.0 or 18.1, etc, would still begin with mycompany.com03, even though the random characters and version number would change. A9B8C... The middle part of a license code is a unique, random mix of letters and numbers. It is different for each license, and changes when a license is upgraded for the next FlexSim version. FSENT signifies the product, in this case FlexSim Enterprise, but you may also see FSEDU for Educational, or OPTQU for OptQuest, etc. Each FlexSim product has a unique product code. 17.1 specifies the version number this license is good for. It can be used to license any FlexSim 17.1.x version or earlier, back to version 5.0. The license won't work for later software versions, like 17.2 or 18.0. For that, the license must have current maintenance and be upgraded for use with the new version. Upgrading Licenses   To use a new year or update release, your FlexSim license will need to be upgraded.   The exact steps for upgrading your license differ based on your type of license:   License Server - Upgrading your hosted licenses Standalone - Upgrading your license If your maintenance agreement has expired, or if you have timed licenses, your licenses will not upgrade. In either case, please contact your local FlexSim representative.   If you install and run a version of FlexSim software greater than your license’s version number, that newer software won’t be licensed, but will run in the feature-limited "Express" mode. To use a fully-featured, licensed copy of the software, make sure that the software’s year.update version number is not greater than your license’s year.update version number (which is typically visible in the license code itself as the final digits of the code - see License Codes above).   Long-term support (LTS) versions   From Wikipedia: Long-term support (LTS) is a product lifecycle management policy in which a stable release of computer software is maintained for a longer period of time than the standard edition.   FlexSim maintains the year release for more than a year, overlapping with the release of the next yearly release for a few months.   Here is an example of how it works:   In December 2017, the current LTS release was version 17.0.11. That same month version 18.0.0 was released. Because 18.0 was brand new, it was not yet considered the LTS version - we let it mature a bit before promoting it to the current LTS. During the time when 18.0 was the latest version, new bugfix releases were added for both 18.0 and 17.0. Finally, in April 2018, 18.1.0 was released. At that time the 18.0 branch was on its 4th bugfix release, 18.0.4, and the 17.0 LTS branch was up to 17.0.13. With the release of 18.1.0 the 18.0 branch was promoted to our current LTS release, and the 17.0 LTS was retired - it receives no further bugfix releases.   As with all future-looking plans, our LTS plan is subject to change. You should not rely on this plan for making purchasing decisions.   Downloading an appropriate version of FlexSim software   To download the version of FlexSim software that best matches your license version:   Log in to your FlexSim Account at https://account.flexsim.com/login/. Visit the downloads page at https://account.flexsim.com/downloads/. Download the latest bugfix release for your license’s version.   If a version of the software most appropriate for your license version is not listed on the main download page, click the More Versions button next to the product matching your license (see screenshot). This will open an expanded view with older versions of that product. Older software versions are not available for download from within unlicensed guest accounts. Additionally, software that has reached End of Life (no support) may no longer be listed for download. Contact your support representative for more information or to inquire about a specific legacy version.     If your FlexSim Account is a guest account (does not own a FlexSim license), only the latest software versions are available for download. Your FlexSim Account must own a license directly, or a license owner can share their license info with you, in order for you to see the More Versions button and have access to download older versions of the software. Visit your Licenses page to see if your account has access to licenses and have them loaded into your account session, then go back to the Downloads page and look for the More Versions button. Older software versions are not available for download from within unlicensed guest accounts.   Model compatibility across FlexSim versions   FlexSim versions are backward compatible, meaning that when a model built in an older year.update release of the software is opened in a newer year.update version, the model is put through an upgrade process that updates the model for use in that later version:     We recommend always saving this updated model under a new file name in order to preserve the original, non-upgraded model file, which you should archive for safe keeping.   FlexSim is NOT forward compatible, meaning that a particular year.update version of FlexSim does not support opening model files saved in newer year.update versions of the software. This is due to changes that are introduced to objects, data structures, added features, etc., that an older version of the software would not support.   A FlexSim model built with a particular year.release version of FlexSim can be opened by any bugfix release of the same year.release version, forward or backward. Bugfix releases do not change objects, data structures, etc., in such a way as to break model compatibility across different bugfix versions of the same year.update FlexSim release.   You should use judgment and care in upgrading models and continuing model development in newer versions of the software. If your simulation team has licenses that have expired at different times, and a colleague is on an older license and you are not able to renew maintenance at this time, you may want to standardize on that lowest version number of FlexSim so that models your team creates and edits can be interoperable among teammates.   FlexSim's model upgrade functionality is fairly robust, but if you are upgrading a model from a version of FlexSim many years older than the version you're opening it in, it may be necessary to open and save the model in an intermediate version (or two). Contact your FlexSim support representative if you encounter any problems upgrading your FlexSim model to a later version.   Opening Files from different versions (Flexsim Version Selector)   If this is a first time install of the FlexSim software, you can double click on any .fsm file and Windows will ask you what software you'd like to open .fsm files. In the program selection scroll down to the version entitled Flexsim Version Selector. This application will automatically open any .fsm file in the version that the file was originally saved or created in.   Alternatively, you can right click on a .fsm file in Windows and navigate to the option Open With > and then navigate to Flexsim Version Selector from here. This will set the version selector application as the primary method for opening .fsm files in the future.  

FlexSim's Webserver is a query-driven manager and communication interface for FlexSim. It allows you to run FlexSim models through a web browser like Google Chrome, FireFox, Internet Explorer, etc. Since the FlexSim Web Server is a basic service to allow FlexSim to be served to a browser, you may decide you want a way to proxy to this service through a full service web server that you can control security and authentication through. This guide will walk you through proxying to the FlexSim Web Server through Apache web server. Install the FlexSim Web Server Program Download and install the FlexSim Web Server from https://account.flexsim.com Edit C:\Program Files (x86)\FlexSim Web Server\flexsim webserver configuration.txt Change the port from 80 to 8080 Start the FlexSim Web Server by double clicking flexsimserver.bat Test the server by going to http://127.0.01:8080 It should look like this: Install Apache Web Server for Windows Download Apache x64 from https://www.apachehaus.com/cgi-bin/download.plx Extract the httpd-<version>.zip file you have downloaded Go into the httpd-<version> folder you have extracted and copy the Apache24 (or Apache25) folder to C:\ Install Apache Dependencies Make sure you have the Microsoft Visual C++ 2008 SP1 package installed. You can get it here: https://www.microsoft.com/en-US/download/details.aspx?id=26368 Download the vcredist_x64.exe package and run the installation Configure Apache Open C:\Apache24\conf\httpd.conf in a text editor Look for the following lines in this configuration file and remove the # character #LoadModule proxy_module modules/mod_proxy.so #LoadModule proxy_http_module modules/mod_proxy_http.so #LoadModule proxy_wstunnel_module modules/mod_proxy_wstunnel.so Those modules should now look like this: LoadModule proxy_module modules/mod_proxy.so LoadModule proxy_http_module modules/mod_proxy_http.so LoadModule proxy_wstunnel_module modules/mod_proxy_wstunnel.so At the bottom of the httpd.conf file, add these 3 lines and save the file: ProxyPass / http://127.0.0.1:8080/ ProxyPassReverse / http://127.0.0.1:8080/ AllowEncodedSlashes On Run Apache Web Server In a file explorer or CMD line prompt, browse to the C:\Apache24\bin folder and run httpd.exe Now that you have the FlexSim Web Server proxied through Apache, you may decide you want to configure Apache to handle security, authentication and customization. Since this is out of the scope of this guide, you can find details on the Internet that can guide you to setting these customizations up. A few resources you may consider: https://community.apachefriends.org/f/ https://stackoverflow.com

Playing Multiplayer Tag in FlexSim! TagServer.fsm TagClient.fsm This is a side project to show off some fun things FlexSim can do using sockets. Sockets are just one possible way that one instance of FlexSim can communicate with another. In its simplest sense, a socket is just a port number and an IP address that computers use to send information to each other. For example, whenever a computer visits a website, it uses sockets to create a connection to the webserver's IP address on port 80 (HTTP) or port 443 (HTTPS). All of this occurs within the framework of the TCP/IP network. Similarly, FlexSim can establish socket connections to communicate with another FlexSim as long as you know the IP address and choose a port for both instances to connect on. Establish Socket Connection In this game of tag, the model that acts as the server uses these commands to set up socket connection with the client: socketinit(); servercreatemain(8002); serveraccept(0); Note: All of the commands in this article can be found in the documentation The client then runs the following to connect to the server. The HostIP should be the IP address of the device running the server model (or 127.0.0.1 if running both client and server on the same machine). socketinit(); int a = clientcreate(); int a_con = clientconnect(a, HostIP, 8002); On both the client model and server model, these commands are in the OnRunStart trigger and the server creates 5 socket connections for each player. 4 for inputs (up, down, left, right) and 1 for passing in their player name from the client. The server model will freeze and wait for all sockets to be set up. For example, if there are 3 players, the server model will wait until 3 clients have successfully ran the client model and connected. After all clients have connected to the server, we can use clientsend() and serverreceive() to send information from client to server. An example of this is sending movement inputs from client to server. This is what that looks like: Client // MOVE if (iskeydown(87)){ clientsend(2, "up"); } if (iskeydown(83)){ clientsend(3, "down"); } if (iskeydown(65)){ clientsend(4, "left"); } if (iskeydown(68)){ clientsend(5, "right"); } Server string up1 = serverreceive(token.Rank * 5 - 3, NULL, 100, 1); string down1 = serverreceive(token.Rank * 5 - 2, NULL, 100, 1); string left1 = serverreceive(token.Rank * 5 - 1, NULL, 100, 1); string right1 = serverreceive(token.Rank * 5, NULL, 100, 1); // token.Rank is the number of the player (1,2,3 etc.) and is used to reference the right // socket for each player's inputs //reset coordinates te.X = 0; te.Y = 0; te.Stop = 0; if (up1 != ""){ // up W meaning the server received an input on this socket te.Y = 1; // this accounts for getting multiple messages from client like "upupup" } if (down1 != ""){ // down S te.Y = -1; // this label is later used in a travel activity } if (left1 != ""){ // left A te.X = -1; } if (right1 != ""){ // right D te.X = 1; } Note: In a typical game environment, the server is also sending information back to the clients, but in this example, all visuals and logic occur on the server. Game Logic All game logic is found on the server process flow. Setup and Order of Models To play Tag, follow these steps: Note: If there are certain firewalls or security groups on your network that doesn't allow traffic into FlexSim outside local networks you may be limited on who can connect to play tag 1. Open TagServer model and change NumPlayers parameter to the desired number of players 2. Open TagClient model and change both global variables (HostIP and EnterNameHere). Again, if everything is running on the same device, use 127.0.0.1 as the HostIP global variable value. 3. Reset and Run the TagServer model first 4. Reset and Run the TagClient model. You should get this output if connection was successful 5. Run clients one at a time for each player until all players have connected and the server will run automatically. This is the output on the server upon successful connection 6. Enjoy!

FlexSim 2017 Update 1 or later is compatible with Windows Mixed Reality headsets and controllers, such as the Samsung HMD Odyssey. To configure such devices, you use the Windows Mixed Reality Portal app in Windows 10 and SteamVR. FlexSim uses SteamVR's OpenVR API to communicate with these devices. Microsoft provides instructions for how to Play SteamVR games in Windows Mixed Reality. I will provide additional summarized steps below: 1. Configure your hardware with the Windows Mixed Reality Portal app in Windows 10. 2. Install Steam. 3. Within Steam, install SteamVR and Windows Mixed Reality for SteamVR. 4. If you are able to do the SteamVR tutorial with your headset, then you should now be able to use VR Mode in FlexSim: Note: While using a Windows Mixed Reality HMD (head-mounted display), pressing the Windows button on the controllers may take you to the Windows Mixed Reality Portal Home: If you end up here, you can take the headset off and put it back on to transfer back to FlexSim: Also, if you appear to be floating far above the ground, you can recenter the headset pose with this script, which you could map to a Custom Button on your toolbar: applicationcommand("recenteroculusrift");

The ideal way to access the User Manual is by viewing an electronic copy either online or inside the software. Online User Manual The User Manual is available online at docs.flexsim.com. There you can select a software version and manual language. We hope to provide additional languages in the future. In-software User Manual There are two ways to open the manual inside FlexSim: Click the User Manual button on the main toolbar. Click the Help menu and then click User Manual. Why the electronic manual is preferred The online / in-software version of the User Manual is better than a print or PDF version for many reasons, including: Regular updates - The electronic version keeps up with every new FlexSim release. A printed manual unfortunately goes out of date every four months with each new release of FlexSim. The online manual allows you to also view older versions of the manual. Animated GIFs - Animations enhance communication by making it possible to see FlexSim in real time. Animated GIFs won't work in a printed copy. Better search - The online version allows you to search the manual using Google. The in-software version also has a search program which is easier than trying to find relevant keywords within a large document. Styled and reflowable tables, images, and tip boxes - While these elements look good on the web, print or PDF versions don't always correctly format their placement within the document. Better organization - A printed manual won’t always maintain the same organization as the online and in-software manual, making it more difficult to navigate. Mini-table of contents - Each topic has easy navigation within each topic via inner-links. A printed or PDF mini-table of contents (found in most topics) can't function as a clickable index, making it difficult to easily skip to relevant sections within a topic. Printing topics from the User Manual While we don't recommend printing the entire manual, you can easily print individual topics for later reference. Print from the online manual Visit docs.flexsim.com using your favorite modern web browser. Use the table of contents in the left navigation bar to visit the topic you want to print. Use the printer button in the upper right of the topic window to print the page: Print from the in-software manual In FlexSim, open the User Manual and browse to the topic you'd like to print. Press the 'world' button to open the topic in your web browser. Choose the print function inside your web browser - depending on your browser, you may be able to right-click the web page and choose Print, or you can use the keyboard combo Ctrl+P.

This article reviews one method for making a state Gantt chart for the default and alternate state profiles: Example Model You can download the model for this walkthrough ( stateganttdemo.fsm). The model has two multiprocessors, in a Group called Multiprocessors. Each multiprocessor has two processes: Process1 and Process2. To make the chart, we will first make a Statistics Collector, and then a Calculated Table. Making the Statistics Collector Make a new Statistics Collector. On the Event Listening tab, use the Sampler to listen to On State Change of the group of multiprocessors. You can leave the parameter names alone. However, we need to add a label, so we can record the profile number. Select the new event, and then use the green plus button in the Event Labels area to add a label for this event. Set its name to ProfileNum, and its value to the following code: data.StateProfileNode?.rank The event settings should look something like the following: Next we need to set the row mode. Make sure it's set to Add Per Event, with no row value. As the final configuration step for the statistics collector, we need to set up the columns. There should be four columns in this collector: Time - In the pick options, select Time, then Model Date/Time Object - In the pick options, select IDs, then ID of Event Object Profile - Type data.ProfileNum for the value. The default storage and display format are fine. State Type the following code: data.eventNode.as(Object).stats.state(data.ProfileNum).profile[data.ToState + 1][1] Set the Storage Type to String The code is necessary because On State Change occurs before the state is set to the new state. So the code is looking up the name of the future state in the profile table. When you reset and run this model, you will see a table like the following: Making the Calculated Table Make a new Calculated Table, and give it the following query: SELECT Object, Time as StartTime, LEAD(Time) OVER (PARTITION BY Object) AS EndTime, State FROM StatisticsCollector1 WHERE Profile = 1 This query creates an Object column as well as a Time column. To get the time that the current state ends, we look to when the next state begins. The LEAD() function looks ahead in the table, and the OVER(PARTITION BY Object) clause makes sure that LEAD() makes sure to look to the next row with the same Object. We also record the state column, and filter out the standard state profile, keeping the special multiprocessor state profile. Once you get this query to work, change the Update Mode to By Interval, and set the interval to 20 or 30. Since the Statistics Collector table will get longer and longer, the query will become more and more expensive as the model runs. To control how much time is spent running the query, we use an interval. The final configuration of the Calculated Table should look like this: You will need to set the Display Format of each column on the Display Format tab (Object, Date/Time, Date/Time, and Raw). Making the Chart Make a new dashboard, and create a Gantt chart. Point it at the Calculated Table. When you do that, the chart should fill in all the other columns correctly. Charting Both State Profiles for Both Objects In order to chart both profiles on the same chart, we first need to add a column to the Statistics Collector, and then update the query in the Calculated Table. The new column should be named ObjectAndProfile, and a Storage Type of String. Use the following code for a value: data.eventNode.name + " - " + string.fromNum(data.ProfileNum.as(int)) Then change your query to the following: SELECT ObjectAndProfile, Time as StartTime, LEAD(Time) OVER (PARTITION BY ObjectAndProfile) AS EndTime, State FROM StatisticsCollector1 With these changes, you should be able to view both profiles for both multiprocessors.

This article borrows from @jordan.johnson's original guide for deploying a distributed experiment/optimization with Amazon. Distributed Terminology Please be familiar with the terminology related to experiments and optimizations. Replication - a distinct model run. We'll use this term below for both replications (experimenter) and solutions (optimizer). Instance - a system, whether virtual or bare-metal, local or remote, meeting FlexSim's recommended requirements, and used for running distributed replications. Main PC - the system from which the user configures and initiates the distributed experiment or optimization. The Cloud - a shorthand term for remote servers/systems hosted in a data center, sometimes by a 3rd party such as Amazon, Microsoft, Google, or others. Background Concepts In discussing distributed experiments or optimization, you should start with a good understanding of both the Experimenter and the Optimizer. Please read and understand this user manual entry which includes explanations of key concepts that will be important as you continue. Other user manual articles provide additional guidance on configuring your own experiments or optimizations. Search the online user manual and this community if you have additional questions regarding experiments or optimizations, as needed. Using the experimenter requires a FlexSim license. The optimizer requires a license for the OptQuest add-on. Please contact your local distributor for more information or to request a test license for FlexSim and/or OptQuest. What are distributed experiments or optimizations? Experiments or optimizations can create dozens, hundreds, or even thousands of distinct model runs (or replications) to test various scenarios, build confidence intervals of the results, or zero-in on an optimal solution. A distributed experiment or optimization takes those individual model runs and assigns them (distributes them) to run across a group of computers. If you needed to run 1000 replications, and you have 4 computers available, each computer could run 250 replications, getting your results 4 times faster. When should you distribute? Using distributed replications can significantly reduce the required time to run an experiment if: The single-run time for your model is high (a couple minutes or more) You anticipate running a high number of replications If the time per replication is short, then the increased communication overhead may outweigh the benefit of using distributed replications. The communication overhead increases because all distributed replications still report results to a single FlexSim process on the Main PC, and that communication occurs over the network (local instances) or internet (remote instances), rather than on a single computer. If an experiment or optimization completes in an acceptable amount of time, you may not need to use distributed replications. Financial Costs 3rd party cloud providers such as Amazon, Microsoft, Google, and others, charge for their services. Your cost is usually based on the hardware you provision for your Windows instances, and the length of time those instances are live. Typically you only run your instances when running your experiment or optimization, and cancel or decommission your instances when your replications are complete. In this way you minimize the cost of your distributed experiment or optimization. The costs and process of decommissioning your provisioned instances differ based on which 3rd party cloud provider you use. You may have access to local computing resources that could be configured for use in your FlexSim experiments or optimizations. In this case you may avoid additional costs relating to 3rd party cloud providers by using your own on-premises computers. Licensing for distributed Windows instances Windows instances used solely for distributed replications DO NOT need an individual FlexSim license. Only the FlexSim installation on the Main PC must be licensed. System requirements for distributed Windows instances Graphics A Windows instance should meet or exceed FlexSim's recommended requirements. However, because replications run as background processes without graphics, they need not meet the graphics requirements and do not need hardware accelerated graphics. CPU An instance can run as many concurrent replications as it has CPU cores. If, for example, an instance has 32 CPU cores, it can run 32 replications of your model simultaneously. RAM For this example of a 32-CPU Windows instance, if you want FlexSim to run 32 replications simultaneously - one on each core - then the instance must also have enough RAM to handle 32 concurrent model runs. On your Main PC, use Windows Task Manager to watch a single model run's RAM usage to determine its peak RAM utilization. If your model's RAM utilization peaks at 3GB throughout the course of a model run, you should make sure your 32-CPU system has at least 32*3 = 96GB of RAM for replications alone, along with a good ~10% more for additional overhead used for the Webserver and the statistics gathering and reporting from all the replications (this number could be more or less, depending on the model's stats gathering). In addition, you must account for your system's baseline RAM utilization - how much RAM it uses just to run the operating system and all its background processes. You can find this baseline by checking the Task Manager at a moment when you're not running any simulations. Add all these together to see how much RAM would be necessary to run a replication on each core of the instance. If your instance doesn't have enough RAM to handle that many simultaneous replications, you'll need to limit the number of CPUs FlexSim will use when configuring your Cloud Computing settings from the Main PC. Disk Disk space is usually not an issue. However, if you are using the Store Data on Hard Drive option in the Statistics Collector, you will need to be sure that there is enough disk space to run the model to completion on the hard drive, multiplied by the number of cores. The amount of disk space on each instance may affect the total cost of using a 3rd party cloud provider. More information See the related sections in the article Recommended System Requirements for a more in-depth discussion of system components such as CPU and RAM, and how they relate to running your simulations and experiments. Provisioning distributed Windows instances The process of provisioning 3rd party cloud instances for running distributed FlexSim replications will differ from provider to provider. FlexSim has guides for the following cloud providers: Amazon Web Services Wherever you decide to host your instances, the important part is that eventually you end up with a group of Windows instances, each with a unique IPv4 address accessible from the Main PC. A custom Windows image Your 3rd party cloud provider probably allows you to save a custom Windows image that can include software and settings that you need for each Windows instance. Doing this once for a custom Windows image saves you time when starting new instances - each instance will start with the software and settings preconfigured for your purpose. On your custom image, do the following Download and install FlexSim. Use the same version of FlexSim as is licensed on the Main PC. Remember, you DO NOT need to activate a license. Run FlexSim. This creates a directory that is needed later. After FlexSim finishes its first start, close FlexSim. Download and install the FlexSim Webserver for your installed version of FlexSim. Edit the Webserver's configuration file appropriately for your situation. Default location is here: "C:\Program Files (x86)\FlexSim Web Server\flexsim webserver configuration.txt" Start the FlexSim Webserver from your Windows Start menu, or manually from the default location here: "C:\Program Files (x86)\FlexSim Web Server\flexsimserver.bat". The Webserver will download necessary files the first time it is run. Close the Webserver after it has completed its initial startup. Allow both FlexSim and node.js through the Windows Firewall. To do so, use Windows' Allow an App through the Windows Firewall tool. You will need to browse for both FlexSim and Node.js. Example locations (exact locations may vary by version): C:\Program Files\FlexSim 2023\program\flexsim.exe C:\Program Files\nodejs\node.exe If you are not familiar with the FlexSim Webserver, please review its documentation and test it out on a local machine to understand what it does, its configuration options, etc. If you cannot configure a custom Windows image, you will need to do the above on each instance individually. Initialize instances Launch your instances. On each instance, do the following: Log in to the instance with Remote Desktop or some other solution. Start the FlexSim Webserver from your Windows Start menu, or manually from the default location here: "C:\Program Files (x86)\FlexSim Web Server\flexsimserver.bat". Note the instance's IPv4 address. Once all instances are running the Webserver, you are ready to configure a distributed experiment or optimization from the Main PC. Author's Note: There is probably a way to make it so that when instances start up, they automatically run the Webserver, so that you don't have to manually connect to each one. I welcome any suggestions or steps for how to make that happen. Configuring a distributed experiment or optimization Once you have a list of running instances available, launch FlexSim on the Main PC. Open the experimenter interface from FlexSim's Main Menu > Statistics > Experimenter. Configure your experiment. As part of your configuration, under the Advanced tab, select the option to Use Distributed CPUs. Press the button to Configure Cloud Nodes. This will open the Global Preferences' Environment tab. Enter the IP addresses of your instances into FlexSim. Enter the port numbers you configured in their FlexSim Webservers. If your instances will max out RAM before CPUs, enter a CPU count representing the maximum number of concurrent replications your instance can handle.

Background   The method for licensing a single-user client PC saves client PC license settings to the Windows profile data of the signed in user, so license settings are saved on a per-user basis.   In cases where the exact number or identity of PC users is not predetermined, such as in a university computer lab, it is impractical to license users individually in this manner. Another use-case for this method is when FlexSim Software is automatically pushed or deployed to client PCs. Having the licensing as part of the deployment is useful.   For this mult-user method we'll use a license file on the client PC to license FlexSim software generally for any user of the PC.   Use a license file   Create a plaintext license file   On the client PC create a plaintext license file named flexsim.lic with the following 2 lines (exclude any line numbers):   SERVER 127.0.0.1 ANY 26914 USE_SERVER   If your Windows settings do not show file extensions, it is possible that your flexsim.lic license file is actually named flexsim.lic.txt, which will not work. Be sure to show file extensions and make sure your license file ends with the .lic file extension. The actual name of the file is not important (it could be helloWorld.lic, for instance), but it needs to end in .lic.   Modify   On the client PC, modify your new license file with the following changes:   On line 1 change "127.0.0.1" to the IP address or fully qualified domain name of your license server. If you modified your license server with custom port numbers, on line 1 replace the default port 26914 with your custom port number.   Install   With FlexSim software installed on a client PC, your new license file should be copied into FlexSim’s installation directory in the following location:   C:\Program Files\FlexSim <version>\program\   Your exact folder path could differ based on custom installation locations or FlexSim version, but it should be placed into FlexSim’s program\ folder.   Multiple license servers?   If your FlexSim licenses/seats are spread across multiple license servers, you can configure your client software to try to pull a license from any of your multiple license servers. Simply create a new license file for each possible license server and save each to the same program\ folder. In this scenario, in your program\ folder you would have multiple license files listed, like this:   flexsim1.lic flexsim2.lic flexsim3.lic etc. Each license file should reference a different license server and its port number.   Next   Check out the next article to learn how to verify that your client PC is licensed, and what to do if it isn't: License Server - Verify client PC licensing.
