Whats New   

The following is a list of features and fixes that have been included in the latest FlexSim releases.

FlexSim 16.0.1

  • Fixed a performance bug with stats_staytime() that was causing models to run slowly.
  • Fixed a bug with Excel export not working for certain columns.
  • Fixed some memory leaks in drawcylinder(), drawcolumn(), drawdisk(), and drawsphere().
  • Fixed an issue with dll nodes sometimes not binding properly.
  • Fixed bugs with excelcreatesheet() and excelsaveas().
  • Fixed a bug with old-structure stateprofiles not resetting properly.
  • Fixed a bug with group objects sometimes being added to charts twice.
  • Fixed a bug with 3D stats not displaying correctly on some objects.
  • Fixed dashboard buttons not saving their text color.
  • Fixed a bug where the hover text for combined stats on Stat charts said average for total values.


  • Fixed a bug with decision points' current content stats.
  • Fixed a bug where items were sometimes not routed to the correct location.
  • Fixed a bug where exit transfers sometimes sent items to the wrong port when multiple items were released.

Process Flow

  • Fixed some statistics bugs in the Zone.
  • Fixed some crashing issues when "Assign To" is given invalid data.
  • Fixed a bug with Batch Label Aggregation to keep strings/arrays/etc. with the Last Value and First Value options.
  • Fixed issues with the Run Animation not allowing you to pass in an array of objects.
  • Fixed an issue with using the wrong instance when pushing/pulling from a List in another Process Flow.
  • Improved 3D mouse performance in the ProcessFlow view.


  • Made the addMember method a dll function so Process Flow can connect travelers to any control point using the Create Object activity.
  • You can now correctly get an AGV's current control point when it finishes OnPreArrival.
  • Fixed an issue with AGV start speeds incorrectly being set to 0 in certain circumstances.

FlexSim 16.0.0 (March 14, 2016)

  • Added options to Global Preferences to define which libraries are visible in the Drag-Drop Library and what order they appear in.
  • Restored the Media Files window (Main Menu > View > Media Files).
  • Added the ability to assign unique random streams to objects in the model using the command getstream().
  • Added a Network Navigator Properties window. (Right-click a NetworkNode to access.)
  • Added a Track Number Field Totals option to the List for stats collection.
  • Added a 'Values Only' data distinction option to the Excel Importer. This data distinction reads number data and string data from excel cells without regard to the cell's formatting (i.e. dates and times are imported as Excel time values).
  • Implemented the excelrangeread() command to import a range of cells using the 'Values Only' data distinction.
  • Added the command convert() for converting model/Excel dates and times.
  • You can now use keyboard shortcuts for debugging. Next Line -> F10, Step Into -> F11, Continue -> F5, Stop Simulation Clock -> Shift+F5
  • Updated object statistics to use Tracked Variables for collecting Content, Input, Output, and Staytime statistics. NOTE: These new statistics are only available for new objects. See the Object Statistics backwards compatbility note below for more information.
  • Made the sql IN clause work if you compare it against a value that is an array.
  • Added trackedvariable() and inittrackedvariable() commands. This allows tracked variables to be created on objects as labels, etc.
  • Tracked Variables can now be accessed using the commands get(), set(), inc(), setnodenum(), getnodenum(), getlabel(), setlabel().
  • Tracked Variables now have a Type which can be Level, Cumulative, Time Series, or Categorical (see inittrackedvariable() documentation).
  • Tracked Variables can now store profiles (similar to state profiles, the profile stores data on the amount of time the tracked variable was at each given value).
  • Improved OpenGL compatibility with older graphics cards and Nvidia Optimus cards.

  • Fixed an issue with copy and paste in the 3D view not maintaining the z position of the copied object.
  • Fixed the Load From File button in the Edit Selected Objects window to call the firecreateevent on loaded objects.
  • Fixed an issue with the dashboard Send To Back not always working.
  • Fixed an issue with the Experimenter Default Reset Scenario combobox.
  • Fixed dashboard snapping.
  • Fixed issues with pasting a node onto another node of a different data type.
  • Fixed an issue with FlexSim sometimes crashing when a dashboard widget was deleted.
  • Fixed a memory leak in the query() command.
  • Backwards Compatibility Note: the following changes may slightly change the way updated models behave.

    • Updated the Combiner so that items can properly exit through port 0 (such as using a Process Flow Load activity).
    • Fixed a bug in the Separator state management that was causing it to be idle when it should be blocked.
    • Changed the max bones per mesh for bone-animated shapes from 60 to 42.
    • Object Statistics: We have changed the default statistics structure for objects in the library. This will not change the structure of existing models, but will now be different for new objects that are created. Specifically, we have made the standard object statistics--namely input, output, content, staytime, and state--use tracked variables instead of the many different object attributes they used previously. This enables us to add new capabilities, such as a content-vs-time graph that exactly reflects the object content changes instead of an interval-based time graph (use the Tracked Variable vs Time chart or the pin button in the Quick Properties Statistics panel), and the ability for Process Flow Wait For Event activites to listen to object content, input, output changes, etc.

      Current FlexSim features will work for both the old and new statistics structures. If you have model or module code that is accessing statistical data directly (such as using commands like get(stats_contentavg(object)) or get(rank(state_profile(object), STATE_IDLE))), this code will continue to work on objects that have the older structure, but it will not work for new objects added to the model. If you want this access to work with objects having the new structure, you should use the getstat() command to get the desired data. The getstat() command will work on both the old structure and the new structure. Below is a list of examples of old statistical access commands vs new getstat() based access.

      OLD: get(stats_contentavg(object))
      NEW: getstat(object, "Content", STAT_AVERAGE)
      (Note here that the getstat() command will return the weighted average that includes the time that the object has been at its current content, whereas with the old method, you had to add that on manually).

      OLD: get(stats_staytimemax(object))
      NEW: getstat(object, "Staytime", STAT_MAX)

      OLD: get(rank(state_profile(object), STATE_IDLE))
      NEW: getstat(object, "State", STAT_TIME_AT_VALUE, 0, STATE_IDLE)
      (Note here that the getstat() command will actually give you the total time in the idle state. This includes the time in its current state if the object is currently idle. With the old method you always had to manually add that in, i.e. get(rank(...)) + (getstatenum(object) == STATE_IDLE ? time() - get(state_since(object)) : 0);

      OLD: getstatenum(object)
      NEW: getstatenum(object)
      The getstatenum() command works on both structures, so you don't need to change it. Alternatively, you can use getstat(object, "State", STAT_CURRENT, 0) (0 is the state profile)

      OLD: getinput(object)
      NEW: getinput(object)
      The getinput() and getoutput() commands work on both structures, so you don't need to change them. Alternatively, you can use getstat(object, "Input", STAT_CURRENT)


    • Added Pull and Send To functionality to conveyors. This is done by connecting multiple objects to a single entry/exit transfer.
    • Added reset position functionality to conveyors.
    • Added additional events to conveyor objects that can be used in connection with the Wait for Event and Event-Triggered Source activites in Process Flow.
    • You can now explicitly remove connections from an entry/exit transfer without it being deleted (using the right-click menu). This is useful when sending flowitems to a list where connections are not required.
    • Straight and curved conveyors now have an optional Virtual Length.
    • Added Priority and Preempt fields to the Exit Transfer.
    • Added a Station object. The Station works much like a Decision Point but also allows you to specify a processing time and optionally call operators.
    • Added States to conveyor objects.
    • Added a CONV_INFO_GET_ACTIVE_ITEM option to the conveyorinfo() command to get a decision point or photo eye's covering item.

  • Fixed decision points and photo eyes not saving to user libraries when adding a conveyor.
  • Fixed conveyor widths not updating when changing conveyor types.
  • Fixed issues not being able to snap decision points to the beginning or end of conveyors.
  • Fixed the conveyor type so new conveyors use the default conveyor type rather than Custom.
  • Fixed the name numbering of decision points and photo eyes.
  • Fixed the Release Area pick option in decision points.
  • Various other bug fixes and improvements to conveyors.
  • Process Flow

    • Added a label filter option for tokens in Quick Properties.
    • Process Flow View now supports a 3D mouse.
    • Updated activity snapping to allow activities to be snapped to the top of other activities.
    • Updated the Release Resource activity to allow a reference to a Resource Shared Asset to be passed into the Resources to Release property.
    • Blocks of activities and display objects can now be saved in User Libraries.
    • Added aligning functionality to the Process Flow view.
    • Added snap-to-grid functionality to the Process Flow view.
    • Speed improvements to drawing.
    • Assign To properties on the Create Object, Push To List, Pull From List and Create Task Sequence can now either overwrite the assigned label's data or insert the data at the front (creating an array).
    • When tying the Resource shared asset to a Group, Dispatcher or Array, the Count property now allows you to utilize any number of those objects. This allows you or the experimenter to easily change the number of available resources without objects being added/removed from the model.
    • Added a 'Do not remove entries from List' option to the Pull From List activity allowing you to utilize the Request and Require fields without removing entries.
    • Tracked Variables can now be added as labels on objects. This allows you to track the history of its values as well as tie it to a Wait for Event activity as a value change listener.

  • Fixed issues with the Finish/Sink activity not properly deallocating shared assets if they still had children in the model.
  • Additional bug fixes and overall improvements.
  • Fixed exceptions sometimes being thrown when dragging connectors around.
  • Fixed the Priority field in the Create Task Sequence activity.
  • Fixed some issues with listening to the OnStateChange of objects.
  • Fixed an issue that caused large numbers of TE/FR instances to take a long time to reset.
  • Fixed an issue with the Resource when using a Local type with each instance having a unique resource reference.
  • Backwards Compatibility Note: the following changes may slightly change the way updated models behave.

    • The Assign Labels activity used to allow you to pass in a treenodearray or a Group so that it assigned labels to multiple objects at once. Now the Assign Labels only accepts one treenode at a time. Passing in a treenodearray will cause only the first entry in the array to have labels assigned to it. To update any old model utilizing this functionality, loop through each object in the array using the Object from Label Array pick option.


    • Updates to AGV travel tasks and preempting.
    • Some minor bug fixes.

    Backwards Compatibility Note: the following changes may slightly change the way updated models behave.

    • AGVs will now read the end speed of the travel task and use it to determine when to finish the task. This means that if you have an existing model where you defined a non-zero end speed of a travel task, older versions would have ignored this, but now the end speed will be simulated properly. Please see the user manual topic on AGV Types for more information on how the end speed is simulated.
    • We changed the AGV preemption mechanism so that:
      1. When you preempt an AGV, if you do not immediately give it a new travel task, it will decelerate to stop after the preemption occurs. In previous versions the preemption mechanism stopped the AGV immediately.
      2. If you preempt an AGV and then immediately give it a new travel task, it will start the new task at the speed it was at before it was preempted. In older versions, a preemption would cause the AGV to immediately stop and then start from speed 0.

    • Changed Copy to also put the path to the highlighted object onto the clipboard and removed Copy Path to Clipboard from the tree's right-click menu.
    • Improvements to the Excel Importer's Automatic Data Distinction option. It now correctly determines if a cell has a number in it but is stored as text. In this case, instead of importing a numeric value of 0, it will import the text as a string.
    • Fixed Time Plots in the dashboard so they clear their data after the warmup time is complete.
    • Fixed a bug with the visual tool inner connections not surviving copy/paste correctly in certain cases.
    • Fixed the visual tool so it can have multiple internal connections go through each other.
    • Fixed the Elevator so the delivery platform properly lines up with wherever the item is being dropped off at.
    • Fix for Task Executers so the endspeed works for offset travel.
    • Fixed fly paths to run in real seconds when not running with the simulation time.

    Backwards Compatibility Note: the following changes may slightly change the way updated models behave.

    • Fixed resource item state variables are now stored with a custom data structure instead of being stored directly in the tree. This means that if you previously accessed an item's fixed resource state directly through the tree instead of using the commands getitemstate(), getitemsendto(), getitemvar(), etc. your model will need to be updated to use those commands.
    • Previously, drawfont() would only change the font for one call of drawtext(). Now, calling drawfont() will change the font and leave it that way until it is changed again.
    • Fixed the 50-flowitem receive limit on the combiner, processor, and rack. This will break old models if your model is dependent on this bug.
    • Null Variants no longer equate with 0 (NULL). We have added the "nullvar" keyword that equates with null Variants. This could affect models that use getlabel() on a label that does not exist. For more information, see getlabel()'s documentation.
    • The following commands now take/return Variants instead of doubles:
      • nodefunction()
      • sendmessage()
      • function_s()
      • function_n()
      • userfunction_s()
      • userfunction_n()
      • nodefunctionlisten()
      • delayednodefunction()
      • addbundleentry()
      • applicationcommand()
      The implications for these changes are as follows:

      nodefunction(x, tonum(current)); // BAD CODE
      nodefunction(x, current); // GOOD CODE

      The problem here is that if you cast it into a number, and on the other side someone wants a node, the Variant thinks it's a number so it won't give back a valid node.
      Additionally, all flexscript and c++ code nodes now return a Variant instead of a double. This also has implications.

      return tonum(centerobject(current, 1)); // BAD CODE
      return centerobject(current, 1); // GOOD CODE

      Here again, if you put something into a number, and then on the other side it wants a node, the variant realizes it's holding a number and won't give back a valid node.
      We have implemented an update script that will search the model for this type of code and will update the code to not use tonum(). The update script logs any changes made, putting the log in the node MODEL:/Tools/CodeUpdateLog.

      The update script will make the following changes:
      1. return tonum(...);
        changes to:
        return (...);
      2. For each of the above mentioned commands, the update will search the model for calls to this command, and will update the parameters as follows:
        nodefunction(theNode, tonum(...), tonum(...));
        changes to:
        nodefunction(theNode, (...), (...));
      However, the update script will NOT catch the following:

      double myVal = tonum(...);
      return myVal;

      double myVal = tonum(...);
      nodefunction(theNode, myVal);

      In saying this, please realize that leaving number casts in these areas may continue to work properly, particularly if you the user control both sides of the pass-off, i.e. you have implemented both the caller side and the callee side. For example:

      Caller side:
      nodefunction(theNode, tonum(theObj));
      Callee side:
      treenode myVal = parnode(1);

      This example should actually work properly. We have deprecated parnode(), parstr(), and parval() and replaced them with a single param() command that returns a type-safe Variant. However, the deprecated commands will essentially try their best to take whatever was passed in and put it into whatever you want. So parnode() will see a number, and try to get it into a treenode. This is the same for returns:

      Callee side:
      return tonum(myObj);
      Caller side:
      treenode myObj = tonode(nodefunction(theNode, ...));

      Again, this should work, because tonode() and tonum() will essentially try to take whatever is there and put it into a number/node.
      Where this will break is where one side is using the type-safe method while the other is not.

      Caller side:
      nodefunction(theNode, tonum(theObj));
      Callee side:
      treenode myVal = param(1); // WILL NOT WORK BECAUSE param(1) IS A NUMBER NOT A NODE

      On FlexSim's side we have moved all (or most) of our code over to using the type-safe method. Thus any calls that interact between FlexSim code and your code should use the type-safe method. We hope that the proactive update script will resolve this for 99.99% of cases.

    • Fixed the DWG importer to properly show the layer colors.
    • Fixed an issue with the model floor not drawing properly.


    • Added an optional "force" parameter to conveyorresumeitem(), which override the stop/resume counting mechanism and force the item to resume.

    • Fixed an issue with not being able to connect network nodes to entry/exit transfers
    • Fixed an issue with doing an inline divert at a point where items accumulate
    • Fixed an issue with items still being rotated when they leave the conveyor system
    • Fixed an issue with transfers from faster to slower non-accumulating sections and the item accumulation at the transfer point.
    • Fixed a bug where items get off-center over time in a conveyor system.
    • Fixed an issue with double-clicking on conveyor transfers.
    • Fixed an issue with feeding items into a Combiner.

    Backwards Compatibility Note: the following changes may slightly change the way updated models behave.

    • Expressions can now be used in select columns of an sql query. In order to do this we needed to change our sql grammar to be more compliant with standard SQL. This means you can no longer use the AS clause in a WHERE or ORDER BY statement. You can now only use AS in SELECT and FROM clauses.
    • Some parameter types for the query command have changed in c++ for more flexible type definitions. This means if you use the query() command in a c++ dll, you'll need to update your dll's headers and recompile the dll. If you use straight c++ compiled code or flexscript for your query() command, then this should just update.

    • 64-bit version (enables FlexSim to use more RAM).
    • Windowing interface overhaul to use a docked window paradigm.
    • Created a Quick Properties docked window that is context sensitive. The window will display the most used properties based on the current selection or the active document window.

      • Updated visual studio wizards that work with VS 2012
      • A module sample tutorial.
      • More Documentation.

    Backwards Compatibility Note: the following changes may slightly change the way updated models behave.

    • Removed 2D Shapes from objects.
    • Removed the Planar view.
    • Many open gl commands have been deprecated. The model update mechanism tries to replace all old usages with the new graphics usages. Usually this should work, but in some cases it may not. Note that glBegin(), glEnd(), glVertex(), glNormal(), glTexCoord() have all been completely deprecated, and eventually will no longer work. Going forward you should use the mesh api.
    • The spaceobject() command has been deprecated and no longer works. In optimizing the graphics engine we realized that a 5-20% refresh rate improvement can be attained simply by removing functionality that is solely there to make the spaceobject() command work. So we've deprecated this command. It is still in the command list so models will update, but updated models that use it will have weirdly drawn shapes.
    • OnLoad is no longer dispatched by the engine when a project/tree is loaded. If you have custom objects that depend on this event, you will need to use some other mechanism to fire logic when the model loads, i.e. through the OnModelOpen, or through model libraries' OnModelOpen.
    • Kinematics functionality has changed so that by default kinematics will automatically be pruned off as you pass their individual end times. Note this required a restructuring of the kinematics data, so if your models don't do it on reset anyway, you'll need to re-initialize kinematics in models that are updated from older versions.
    • In previous versions, getdatastat() was documented incorrectly for the parameter p2 (degrees of freedom). It was actually interpreting p2 as the number of samples in the set, not degrees of freedom. We've fixed that by simply not using that parameter and inferring the number of samples/degrees of freedom from other parameters. This means if you used this command previously it will return different/better results in this version. Also we've changed the way the confidence interval "clamps" to percentages in order to be "safer". Again this affects the values that were returned in previous versions vs this version. See the command documentation on getdatastat() for more information.
    • We changed the name of the class FlexsimObject to FlexSimObject in-line with our naming scheme going forward. We have implemented an update script that replaces all instances of "FlexsimObject" with "FlexSimObject" in updated models. This means if certain things in your model are dependent on the name "FlexsimObject" (I don't know what that could be, except for maybe dll code that uses the name FlexsimObject) there may be issues with the update.
    • The assimp 3ds importer is translating some of the files (namely the robot clamps) in a way that is different than our old 3ds importer. It is possible that other 3ds files may need their offsets manually adjusted after updating.
    • Fixed the per-event 50-flowitem receive limit on the queue. This will break old models if your model is dependent on this bug.
    • Fixed a bug with deceleration on a network when the task executer is blocking space and is given two travel tasks in a row (this might change old models)
    • Several attributes were removed, so if you use these attributes in your model you will need to update your model properly:
      • Removed Attributes: assertshape, asserttexture, billboard, distcutoff, events, instances, OnCaptured, OnCollision, OnInterrupted, state_graph, state_histo, state_percent, stats_contenthisto, stats_customgraphs, stats_throughputgraph, stats_throughputgraphmaxpoints, stats_throughputhisto, tables, textureaxis_s, textureaxis_t, travelstarttime, traveldirection, travelendtime, traveltimealpha, traveltimebeta, travelvpeak, traveldistance, travelstartx, travelstarty, travelstartz, travelendx, travelendy, travelendz, travelvmax, travelacc, traveldec
      • Removed Draw Attributes: ignoredraw, ignorezbuffer, nochildrotate, nochildscale, noondraw, nopredraw, shapetype, reflective, luminous
      • Removed Commands: travelto, traveltoupdate, ntravelto, ntraveltoupdate

    • Enhanced the experimenter to use multiple cores.
    • Added a new web browser GUI widget.
    • Added a new Dashboard window with HTML5 canvas statistics graphs.
    • Redesigned the experimenter interface to integrate the new statistics objects.
    • Added new experiment variable options "number of objects in group" and "number of task executers."
    • Developed web accessibility: Opening, configuring, running, and viewing models over the web (using a web browser or handheld device).
    • Added a new AutoCAD dwg importer.
    • Added model units and conversion windows. When building a new model, a screen will ask you what model units you will be using. When updating an old model, a screen will ask you what model units were used to build the old model. These settings are stored in the Tools folder of the model.
    • Modified the picklist and trigger gui widgets to be easier to use.
    • Created a new node datatype (DATATYPE_BUNDLE) for storing large amount of information efficiently (see documentation of bundle commands).
    • Implemented a way to package media (3D shapes and bitmaps) into the model file so that you only need to distribute one file instead of a whole directory of files.
    • Added an embedded command documentation window that can be opened by highlighting a command and pressing F1 in the code window or tree view.
    • Added a FlexScript call stack to the debugger.
    • Added a step-in function for FlexScript user commands and nodefunctions in the debugger.
    • Added a logic builder interface for writing FlexScript logic without writing code. (You can change the default editor back to Code by unchecking 'File > Global Preferences > Environment > Use Logic Builder by Default'.)
    • Enhanced the flexibility of pull logic and added a new pullitem() command for use in the Pull Strategy trigger.
    • Improved templates to allow for popup gui windows on picklist options.
    • Added a mechanism for multiple state profiles.
    • Changed tables to always show the headers despite scrolling.
    • Fixed a bug that was messing up the save operation when out of memory.
    • Toggled the large-address-aware switch so that FlexSim can allocate more memory.
    • Added floor() and ceil() commands.
    • Added a switch for hashing the node's subnodes' names for quick lookup.
    • Added an option in the Labels tab so that labels' values can be automatically reset.
    • Other various fixes from the development list.

    Backwards Compatibility Note: the following changes may slightly change the way updated models behave.

    • Fixed a critical bug in curved network length calculations.
    • Fixed issues with gettenetnode() and distancetotravel() on TEs that use "do not travel offsets and block network space."
    • Made a change to distancetotravel() to base the "back-to-node" distance on the center of the object instead of the object's location.
    • Changed pulling to no longer override the send-to. Now both send-to and pull must check out to transfer a flowitem.
    • Changed receiveitem() so that it doesn't behave as if it were pulling.
    • Made the Rack's OnEntry trigger fire before evaluating the dwell time.
    • Added a new random number generator to generate seeds based on the replication number for the existing random number generator. Email support if you need a script to initialize the streams of a particular model back to the values used in prior versions.
    • Added a new overload to the command tonode() to handle large memory addresses. Dlls will need to be recompiled with updated headers to obtain this fix.
    • Fixed a bug where an endspeed of 0 wasn't properly telling a task executer to continue at full speed at the end of a travel task. The behavior now correctly matches the documentation.
