FlexSim 2017 Update 2 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 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. Included fixes listed in 17.1.5. 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.

FloWorks 17.2.0 will be released in parallel with FlexSim 2017 Update 2. This new version of FloWorks has some major changes to align it with recent updates to FlexSim, such as dot syntax, Process Flow templates, and a revised user manual. Therefore we are releasing it as a public beta. The latest beta version, released August 21, can be found in the Downloads section of your FlexSim account on the 3rd party modules tab. Click "More Versions" to show the Beta release. Please do not hesitate to report any bugs, usability improvements and feature requests to [email protected]. About FloWorks FloWorks is a 3rd party module developed and maintained by Talumis BV (talumis.com). It provides faster and more accurate modelling and calculation of fluid systems than the default FlexSim fluid library. It is especially useful within the oil, gas, and bulk industry both for production and supply chain optimization. This module requires a FloWorks license with active maintenance. For any questions, please email [email protected]. Release notes Note: the bug fixes will also be available in versions 17.1.3 and 17.0.6, where applicable. Added FlowObject class interface ("dot syntax") for majority of FloWorks objects. Can now access products by name when using FloWorks product table (e.g. source.product = "Raw material" instead of source.product = 3 ). Can define recipes for products in the products table and dynamically load / execute them on Flow Mixers. Added Process Flow templates for mixers executing production schedule and flow tank with cleaning / certification. Updated Pin to Dashboard buttons to use Statistics Collectors to collect data. Revised most of the user manual (tutorials are missing, will be re-released in a future version). Bug fix: Calling SelectFlowIp and SelectFlowOp with multiple ports produced FlexSim error. Bug fix: When using a product table, sometimes the Product dropdown would not show the correct product when opening Properties. Bug fix: Flow Conveyor would not suspend correctly when output flow restricted.

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.

Update June 27, 2017: Upgrade versions FloWorks 17.1.2 and FloWorks 17.0.5 are now available. These releases resolve an incompatibility that may result in errors on starting FlexSim when you install FloWorks in combination with certain other modules. If you want to use the (beta version of) the Emulation module, for example, you should upgrade FloWorks to this latest version. There are no functional changes. If you are using the LTS version (17.0.5) of FlexSim you should upgrade to FloWorks 17.0.5. Download FloWorks 17.1.2 if you are using FlexSim 2017 Update 1 (FlexSim 17.1.2). Both versions can be found in the Downloads section of your FlexSim account on the 3rd party modules tab. Bugs may be reported to [email protected]. About FloWorks FloWorks is a 3rd party module developed and maintained by Talumis BV ( talumis.com). It provides faster and more accurate modelling and calculation of fluid systems than the default FlexSim fluid library. It is especially useful within the oil, gas, and bulk industry both for production and supply chain optimization. This module requires a FloWorks license.

Release notes From FloWorks 17.0.4 to 17.0.5, and from FloWorks 17.1.1 to 17.1.2: Bug fix: Fixed errors when loading FloWorks with other modules dependent on Process Flow, such as the Emulation module. From FloWorks 17.0.3 to 17.0.4, and from FloWorks 17.1.0 to 17.1.1: The following bug fixes and usability improvements are available in both versions: Bug fix: Flow Conveyor with multiple inputs sometimes created too many update events. Bug fix: Flow Conveyor now allows input port at end of conveyor. Usability improvement: Pick list options updated to dot syntax, e.g. centerobject(current, 1) is now current.centerObjects[1]. Usability improvement: Changed object list dropdown to be more descriptive about input, output and center connections. Usability improvement: Changed input/output amount trigger template to increase current input/output instead of previous trigger amount Usability improvement: Added FloWorks options to User Event code dropdown. The following bug fixes apply to version 17.1.1 (FlexSim 2017 Update 1) only. Bug fix: Fixed exception when changing to first product of product table using scripting (thanks to Julio for reporting it) (product table is only available in FloWorks 17.1). Bug fix: Flow To Item releases item when pulling object downstream is unblocked (Bug was only present in FlexSim 17.1). Bug fix: Flow To Item now uses item.Type labels instead of deprecated setitemtype (getitemtype/setitemtype was deprecated in FlexSim 17.1).

The FloWorks module has been updated for FlexSim 2017 Update 1 and FloWorks 17.1.0 is now available (10 April 2017). This release contains new features (see the Release Notes section below). It does not work with the LTS version of FlexSim 2017 (17.0.x). The upgrade version FloWorks 17.0.3 has been released for FlexSim 2017 (17.0.4). It contains all the bug fixes from FloWorks 17.1.0 but it does not contain new features and does not work with FlexSim 2017 Update 1 (17.1.0). NOTE: Due to a change in FlexSim, a new version was released on April 12. If you are using FlexSim 17.0.0 - 17.0.3, please use FloWorks 17.0.2, which is functionally identical. Both versions can be found in the Downloads section of your FlexSim account on the 3rd party modules tab. Bugs may be reported to [email protected]. About FloWorks FloWorks is a 3rd party module developed and maintained by Talumis BV ( talumis.com).

Note that FloWorks 17.1.0 may require an upgraded license, see the Release Notes below. For any questions, please email [email protected]. Release notes FloWorks 17.1.0 (April 11, 2017) This version of FloWorks supports FlexSim version 17.1.0. Added a multi-compartment loading controller to allow multiple tanks on the same Task Executer to be loaded in sequence and/or in parallel. Added the mass flow conveyor, an accumulating version of the Flow Conveyor. Instead of using numeric product IDs, you can now pre-define a product table in your model, with fixed product names and colors. See the Products page in the FloWorks User Manual for more information. As of now, FloWorks license versions will need to be upgraded with every release, similar to your FlexSim license. (Existing users will automatically be requested to upgrade their license using the Request Upgrade button in the FlexSim License Activation window.) All bug fixes included in version 17.0.2, see below. FloWorks 17.0.3 (April 12, 2017) Version 17.0.3 of FloWorks supports FlexSim 2017 LTS versions 17.0.4 and onwards. This version is a re-release of FloWorks 17.0.2 (see below) due to a change from FlexSim 17.0.3 to 17.0.4. Which FlexSim version are you using? Which FloWorks version should you download? 17.0.0, 17.0.1, 17.0.2, 17.0.3 17.0.2 17.0.4 (LTS) 17.0.3 17.1.0 17.1.0 FloWorks 17.0.2 (April 11, 2017) This version of FloWorks supports Flexsim versions 17.0.0 - 17.0.3. Bug fix: Code headers correctly use Object instead of treenode for current and item so pick list items like "Object connected to center port" work again. Bug fix: Utilization no longer reported as -100% for object with maximum flow set to 0 on reset. Bug fix: Flow control no longer breaks down indefinitely once run with one connected object. Bug fix: Fixed exception when copy/pasting object with Flow Arrows enabled. Bug fix: Added missing icons for options in FloWorks submenu of Toolbox. Bug fix: Flow Conveyor now correctly detects changes in ratio of incoming components where total flow stays the same. Bug fix: ChangeTeEdgeSpeed command no longer throws exception when used on Task Executer not attached to Travel Network. Bug fix: Berth and loading point clear their contents on reset, like all Fixed Resources do.

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.

The FloWorks module has been updated for FlexSim 2017 and is now available (December 2016). Update 1: Bug fix update 1 was released on Jan 23, 2017. Update 2: Bug fix update 2 and FloWorks 17.1 for FlexSim 2017 Update 1 were released on Apr 11, 2017. FloWorks is a 3rd party module developed and maintained by Talumis BV ( talumis.com). It provides faster and more accurate modelling and calculation of fluid systems than the default FlexSim fluid library. It is especially useful within the oil, gas, and bulk industry both for production and supply chain optimization. This module requires a FloWorks license. For any questions, please email [email protected]. Release notes FloWorks version 2017.0.1 (Jan 23, 2017) Bug fix: Missing names and items in Flow Item Bin fixed. Bug fix: Properties window for Flow Tank flow item now opens correctly. Bug fix: Resolved some minor issues with "Add to dashboard" pins. FloWorks version 2017.0.0 (Dec 22, 2016) FloWorks updated for FlexSim 2017 Flow Mixer now has a manual mode, that will put it in Idle mode after each batch until you manually call StartMixerRecipe. Allow Input Rate and Output Rate to be plotted versus time. New Workability and Level Triggered Event objects added with focus in particular on modelling of ports and offshore processes. Unfilled part of Flow Tank is no longer necessarily gray but takes the object color. When Impact Events are active on a FloWorks object, they will show a box around the object similar to the "stopobject" behavior in standard FlexSim. The color of the box varies from red (0) through yellow to green (1) to black (infinity) depending on the impact factor of the event. Dropdown lists for port actions improved. For example, you can now open or close a single port (OpenFlowIp c.s.), select an individual port to open, close input and open output, etc. Increased limits on number of objects and events when running unlicensed version in FlexSim Educational version. Bug fix: Can now add Object Groups to FloWorks charts. Bug fix: When changing a Flow Task Executer from vessel to truck, the TE's flow tank is correctly scaled and positioned on reset. Bug fix: The State display in the Quick Properties did not correctly show the state of the Loading Arm. Bug fix: Arrow heads can now be dragged by holding 'X' key instead of Alt. User commands consolidated and documentation updated: ConnectFlowObjectToOtherObject command rewritten and documented. All documentation in modules\FloWorks\help\Commands reformatted and automatically generated based on actual user commands. These help pages often provide more explanation on the parameters and their optional values, the return types, and more extensive examples than the FlexSim Command Helper pages. Integration with the Process Flow module: FloWorks options added to "Listener Initialized" trigger of "Wait for event" action. Dropdown lists for port actions improved. For example, you can now open or close a single port (OpenFlowIp c.s.), select an individual port to open, close input and open output, etc. Backwards Compatibility Note: the following change may slightly change the way updated models behave. The Item To Flow's OnItemEmptied trigger is now fired before the actual item is destroyed, so that you are still able to reference it in the trigger code.

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).

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.
