FlexSim 2017 Update 2 Beta is available. (updated 22 August 2017) To get the beta, log in to your account at www.flexsim.com, then go to the Downloads section, and click on More Versions. It will be at the top of the list. 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 Reorganized the User Manual and updated its formatting. Added more topics, tutorials, and reference pages to the User Manual. Added new Statistics Collector and Calculated Table tools. Added new generic charts for plotting statistics gathered with Statistics Collectors and Calculated Tables. Updated the pin to dashboard buttons to create and use Statistics Collectors instead of the legacy charts. Added a Variant constructor and assignment operator to Vec3 and Color classes. Added functionality for copying dashboard charts as images, and pasting images into dashboards. Added new interfaces to FlexScript, such as Math, Group, and DateTime. Added toNum() and fromNum() methods to the string class. Added a setState() method to the Object class that will work correctly with listening to state changes. Improved handling of read-only model files. Keyboard shortcuts (Ctrl+PageUp and Ctrl+PageDown) and additional enhancements for switching tabs. Added the ability to have null values in a bundle. Added the ability to make kinematics exclude incline rotation when managing rotations. Improved the parenthesis and quote autocomplete functionality. Added autocomplete for curly and square brackets. Added a new print() command to write to the output console more easily. Added support for instanced meshes. Updated the animation system so a single shape can have multiple animators from different shape files. Changed the assimp 3D importer so that it can extract and load embedded textures. Added support for using specular maps and gloss maps. Added support for FlexScript dot syntax in SQL queries. Added the capability to specify a warmup time in the interactive model run. Added options for following objects with the view. Improved MTBF/MTTR state listening to use less events and be more precise. Updated the Network Navigator to work for an object that is inside a container that is connected to the network. Fixed a bug with global variable highlighting and autocomplete. Fixed an issue with destroying a TE on a network when it blocks space on the network. Backwards Compatibility Note: the following changes may slightly change the way updated models behave. Fixed a bug with min() and max() when using distribution functions. Previously, getting the number of columns in a Global Table using Table.numCols or gettablecols() returned 0 when the number of rows was 0. Column headers and data types are preserved even when there is no row data. These commands now return the number of columns. Changed operators to not change their incline rotation when traveling on inclines. This will change location calculations if you have advanced logic based on internal operator locations. NodeListArrays like Object.outObjects can no longer be implicitly cast to an Array. Use the toArray() method instead. Fixed a bug with animations drawing their first frame instead of their last frame at times beyond the endtime. Added a special rule for ambient color {0, 0, 0} to not use the ambient color. This change will make shapes with ambient {0,0,0} to appear brighter. Change the ambient color to a dark gray, such as {1,1,1} if you want them to remain dark. Fixed a bug in the shader that dulled specular highlights with the diffuse texture. This may change how shapes look; they may appear shinier now. Added the IS NULL and IS NOT NULL clauses to SQL. Math and comparison operators on null values now return NULL. FlexSim's SQL execution engine is now more in line with the SQL ANSI standard regarding null values. Specifically, if you do comparisons or math operations on elements that have null values, this will return null values. This is different than in FlexScript, where a null value acts like 0 in math operations. Also, null values will be ignored in aggregation functions like AVG(). An option to use legacy SQL nulls was added to Model Settings to preserve backwards compatibility. Upgraded models will automatically enable this option, but new models will default to using the SQL ANSI standard for nulls. Added support for more SQL query operators, such as the case-when-then-else-end operator and window functions. This adds many new keywords to SQL, meaning that if you used these as column names in older queries, they will create syntax errors in the query parser in this version. To fix this, put square brackets [] around the column name. Changed accessing dynamic label properties to use evaluate() instead of value. For example, consider the following code sample: Variant value = current.MyLabel; In 17.1 and previous, this code was the same as: Variant value = current.labels["MyLabel"].value; In 17.2 we changed it so that this code is now the same as: Variant value = current.labels["MyLabel"].evaluate(); The difference is in how FlexScript-toggled node values are retrieved. In 17.1 and previous, current.MyLabel would have just given the text that is the FlexScript code. In 17.2, retrieving current.MyLabel will actually evaluate the FlexScript as code. This is consistent with how table values are accessed. If you have old code that explicitly tried to get the code text with current.MyLabel, you will need to update that code in 17.2 to use current.labels["MyLabel"].value. Process Flow Added a Material Consumption and Replenishment template. Added functionality for pasting images into Process Flow views. Conveyor Added a Gap-Optimizing Merge Controller Process Flow template. Added instanced rendering to improve Render Mode performance. Changed Render Mode to be enabled by default. Added new visual options for conveyors. Improved run speed performance of the Conveyor Module. AGV Added unload-to-empty capability to the AGV Process Flow template. AStar Added a bridge element to the AStar network. Added functionality for collision avoidance. Improved heat maps for analyzing AStar traffic. Backwards Compatibility Note: the following changes may slightly change the way updated models behave. Changed the path finding algorithm for the AStar navigator. When you tell an AStar traveler to travel to an object, now it will behave more like the default navigator. It will calculate a "threshold radius" around the object, based on the object's size. Then it will only travel to the edge of that radius. This makes it work better especially for loading/unloading to/from rack objects. The travel operation won't commit as much to traveling to the center of the object,because that can be left to the load/unload operation, which determines exactly where in the rack to pick/place the item. However, this change does affect how older models work because it changes the routes that travelers take.

FlexSim 2017 Beta is available. (updated 30 Nov 2016) To get the beta, log in to your account at www.flexsim.com, then go to the Downloads section, and click on More Versions. It will be at the top of the list. 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 Improved FlexScript performance by compiling and executing it as machine code instead of interpreted bytecode. Added new syntax to FlexScript for accessing objects' methods and properties, including dynamic label access. Improved OpenGL compatibility by removing many deprecated function calls and adding support for the OpenGL Core Profile. Added a mechanism for loading DWG data into the tree using the Model Background object. Added a new Snap to Background setting on the 3D view for snapping to points loaded from a DWG file. Upgraded the licensing system to Flexnet Publisher 2016 R1 (11.14). Changed the network licensing system so that you can open multiple FlexSim instances using only one license seat. Added a Quick Library popup to Dashboard views. Added Travel to Location pick option to OnResourceAvailable. Added Export Results to CSV pick option to the End of Experiment trigger Fixed some issues with auto-complete not displaying correctly. Fixed a crashing bug with settablesize() on tables with bundle data. Process Flow Added functionality for snapping activities into the middle of a block. Improved the Activities window, including renaming activities, better filtering options, and locating label references. Added a Billboard setting for Text objects. Added a right-click Edit Activity Visuals option. Added an option to the Create Object activity for positioning an object at another object's location without moving into that object. Added a Preserve Global Position checkbox to the Move Object activity. Updated the Schedule Source table so that it can add labels. Updated the Release Token activity to allow numbers and strings. Backwards Compatibility Note: the following changes may slightly change the way updated models behave. The new version of Flexnet Publisher requires network license servers to be upgraded. They need to use the latest vendor daemon and update the Flexnet Licensing Service. More information can be found in the license upgrade instructions at https://www.flexsim.com/ftp/LicenseServer/ Updated the Separator's order of events (executing OnEntry before Setup Time) to be consistent with the Processor. Users of the mesh api should update usage of GL_QUADS to use GL_TRIANGLES instead. GL_QUADS is deprecated and will not work when using the OpenGL Core Profile. Since the new FlexScript parser compiles to machine code, the order in which parameters are evaluated has changed to be aligned with the x86/x64 calling convention. This means models containing code where parameter evaluation order is important may have changed results. For example, the following code will have different results: myusercommand(duniform(1, 5), duniform(1, 10)) In the x86/x64 calling convention, parameters are evaluated from last to first. In this case, the duniform(1, 10) call will be called first. Since this call changes the state of random stream 0, changing the order of parameter evaluation changes the result. The new parser has a stricter grammar for the == and != comparison operators. The types of the operands must be the same or related. For example, the following code will now give compile errors because it is comparing unrelated types: double x = 0; treenode y = model(); if (x == y) { } This version introduces a new Array type, which is an array of variants, enabling a more feature rich array usage. In doing this, we are deprecating the old array types of doublearray, intarray, stringarray, and treenodearray. Specifically, the old array types are now just aliases for the standard Array type. This means that you can now, technically, put a string into a doublearray and vice versa, because they are all just Arrays. Hence we encourage you to just use Array in your code instead of the old array types. This change has also introduced a problem regarding the Variant type. In previous versions, the Variant could hold each of the four types of arrays, and it had a type value associated with each type, which you could get with the getvartype() command, comparing that value to one of VAR_TYPE_INTARRAY, VAR_TYPE_DOUBLEARRAY, VAR_TYPE_STRINGARRAY, or VAR_TYPE_TREENODEARRAY. Now, however, since we've merged all of those types into one, all of those values would theoretically be the same value, introducing issues if you had code that switches on getvartype(), or in some cases if you had a series of if/else compares on that value. Depending on the specific nature of that code, it would be hard to predict exactly how that code would behave going forward. Thus, we have decided to get rid of those old macros for each array type. Now there is just the macro VAR_TYPE_ARRAY. If you have existing code that uses the older macros, you will get compile errors when you open your model in version 17.0. We do this specifically so that you will be notified of code that needs to be updated. There are also several pick list options in the process flow module that use these older macros. Version 17 includes update scripts that will hopefully update all of those pick options in existing models to use the new VAR_TYPE_ARRAY macro instead of the old macros. With the new FlexScript parser, there are now some differences with how the parser compares a null variant to 0. In the old parser, the following expressions applied: (nullvar == 0) is false (nullvar <= 0) is true (nullvar >= 0) is true In the new parser, the following expressions apply: (nullvar == 0) is false (nullvar <= 0) is false (nullvar >= 0) is false This brings the <= and >= operators inline with the == operator. However, old code will evaluate differently now. The following expressions apply in both the new and old parsers: (nullvar < 1) is true (nullvar > -1) is true The param() command will now return nullvar if the parameter number is greater than the number of parameters passed to the function (previously it returned 0).

FlexSim 2017 is available. If you have bug reports please email [email protected] or post a new question to this answers site. If you have suggestions or new feature requests, create a new idea in the Development space. Release Notes Improved FlexScript performance by compiling and executing it as machine code instead of interpreted bytecode. Added new syntax to FlexScript for accessing objects' methods and properties, including dynamic label access. Improved OpenGL compatibility by removing many deprecated function calls and adding support for the OpenGL Core Profile. Added a mechanism for loading DWG data into the tree using the Model Background object. Added a new Snap to Background setting on the 3D view for snapping to points loaded from a DWG file. Upgraded the licensing system to Flexnet Publisher 2016 R1 (11.14). Changed the network licensing system so that you can open multiple FlexSim instances using only one license seat. Added a Quick Library popup to Dashboard views. Added Travel to Location pick option to OnResourceAvailable. Added Export Results to CSV pick option to the End of Experiment trigger Fixed some issues with auto-complete not displaying correctly. Fixed a crashing bug with settablesize() on tables with bundle data. Process Flow Added functionality for snapping activities into the middle of a block. Improved the Activities window, including renaming activities, better filtering options, and locating label references. Added a Billboard setting for Text objects. Added a right-click Edit Activity Visuals option. Added an option to the Create Object activity for positioning an object at another object's location without moving into that object. Added a Preserve Global Position checkbox to the Move Object activity. Updated the Schedule Source table so that it can add labels. Updated the Release Token activity to allow numbers and strings. Backwards Compatibility Note: the following changes may slightly change the way updated models behave. The new version of Flexnet Publisher requires network license servers to be upgraded. They need to use the latest vendor daemon and update the Flexnet Licensing Service. More information can be found in the license upgrade instructions at https://www.flexsim.com/ftp/LicenseServer/ Updated the Separator's order of events (executing OnEntry before Setup Time) to be consistent with the Processor. Users of the mesh api should update usage of GL_QUADS to use GL_TRIANGLES instead. GL_QUADS is deprecated and will not work when using the OpenGL Core Profile. Since the new FlexScript parser compiles to machine code, the order in which parameters are evaluated has changed to be aligned with the x86/x64 calling convention. This means models containing code where parameter evaluation order is important may have changed results. For example, the following code will have different results: myusercommand(duniform(1, 5), duniform(1, 10)) In the x86/x64 calling convention, parameters are evaluated from last to first. In this case, the duniform(1, 10) call will be called first. Since this call changes the state of random stream 0, changing the order of parameter evaluation changes the result. The new parser has a stricter grammar for the == and != comparison operators. The types of the operands must be the same or related. For example, the following code will now give compile errors because it is comparing unrelated types: double x = 0; treenode y = model(); if (x == y) { } This version introduces a new Array type, which is an array of variants, enabling a more feature rich array usage. In doing this, we are deprecating the old array types of doublearray, intarray, stringarray, and treenodearray. Specifically, the old array types are now just aliases for the standard Array type. This means that you can now, technically, put a string into a doublearray and vice versa, because they are all just Arrays. Hence we encourage you to just use Array in your code instead of the old array types. This change has also introduced a problem regarding the Variant type. In previous versions, the Variant could hold each of the four types of arrays, and it had a type value associated with each type, which you could get with the getvartype() command, comparing that value to one of VAR_TYPE_INTARRAY, VAR_TYPE_DOUBLEARRAY, VAR_TYPE_STRINGARRAY, or VAR_TYPE_TREENODEARRAY. Now, however, since we've merged all of those types into one, all of those values would theoretically be the same value, introducing issues if you had code that switches on getvartype(), or in some cases if you had a series of if/else compares on that value. Depending on the specific nature of that code, it would be hard to predict exactly how that code would behave going forward. Thus, we have decided to get rid of those old macros for each array type. Now there is just the macro VAR_TYPE_ARRAY. If you have existing code that uses the older macros, you will get compile errors when you open your model in version 17.0. We do this specifically so that you will be notified of code that needs to be updated. There are also several pick list options in the process flow module that use these older macros. Version 17 includes update scripts that will hopefully update all of those pick options in existing models to use the new VAR_TYPE_ARRAY macro instead of the old macros. With the new FlexScript parser, there are now some differences with how the parser compares a null variant to 0. In the old parser, the following expressions applied: (nullvar == 0) is false (nullvar <= 0) is true (nullvar >= 0) is true In the new parser, the following expressions apply: (nullvar == 0) is false (nullvar <= 0) is false (nullvar >= 0) is false This brings the <= and >= operators inline with the == operator. However, old code will evaluate differently now. The following expressions apply in both the new and old parsers: (nullvar < 1) is true (nullvar > -1) is true The param() command will now return nullvar if the parameter number is greater than the number of parameters passed to the function (previously it returned 0).

If you have bug reports or other feedback on the software, please email [email protected] or create a new idea in the Development space. FlexSim 21.2.0 Release Notes Added a Template system for inheriting properties from other objects. Added new manipulation handles for moving, rotating, scaling, and connecting objects in the 3D view. Added ability to delete connector lines. Added a StateTable object. Added a getstatetableutilization() command. Added a Pass-through parameter type. Added a checkbox so transporters can move their forks separate from traveling. Added more Task Executer shapes. Improved treenode.getPath() to return a relative path to nodes that aren't a direct ancestor. Added a Frustrum Culling checkbox in Visuals. Agent Added an AgentSystems property. AGV Allowed the user to define some basic routing cost multipliers, including: An option to divide by speed, allowing for fastest path routing (instead of shortest path) An option to define a custom path-based multiplier to the cost Added Path Conditions, which allow you to "close" certain paths, based on either model state or agv state, etc. Added a Prioritize Control Point Lookahead option. A* Added the capability to have oblong grid node sizes. Allowed barriers to be inside visual tools. Added the ability to add dynamic barriers to the A* system. This is done by calling AStar.navigator.addDynamicBarrier(), then AStar.navigator.removeDynamicBarrier() to remove those barriers. Added several triggers to A* objects: AStar.Navigator: OnGridChange: called when dynamic barriers are added or removed AStar.Traveler: OnCalculatePath: called just before a traveler's path is being calculated AStar.Traveler: OnNavigatePath: Called just before a traveler runs the algorithm to define kinematics and cell allocations for traveling its path. Also allows the ability to override the default behavior and define your own. Made several additions to AStar.Traveler API, AStar.Navigator API, etc. Added a TravelPatterns property. Backwards Compatibility Note: The following changes may slightly change the way updated models behave. Improved the deadlock recovery algorithm. Now it will add each traveler in the deadlock, as well as any travelers that are waiting on those travelers, as dynamic barriers. Then it will go through each traveler in the deadlock, remove it from the dynamic barriers, add any additional travelers that are adjacent to that traveler as barriers, then try to recalculate the path to the traveler's destination. If it finds a traveler that can still travel all the way to its destination, that traveler will be rerouted. Otherwise, if it finds a traveler that can travel at least on grid square, it will reroute that traveler. Otherwise, it will give a notification of unrecoverable deadlock. GIS Added the GIS module to the Flexsim Installer. Process Flow Added a ProcessFlows property. Added a ProcessFlowVariables property. Backwards Compatibility Note: The following changes may slightly change the way updated models behave. Removed instance object editing from Object Process Flows.

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 17.0.3. 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.
