Exporting a Model to Binary

You can export models to Binary format suitable for use with a range of simulation tools. The result is a stand-alone Binary code model possible to use on any platform without the need for a license on the target system.

This task shows you how to:

Before you begin: To export to a Binary free of any licensing, you must have the Systems FMU Export license. For further information on licensing, see the Dassault Systèmes License Server Essentials Guide.

Export by an Interactive Function

You can export a model to Binary using an interactive function.

  1. Open the ExternalInterfaces library by searching for it, see Open with Search.
    The ExternalInterfaces library is added to the list in the Package Browser.
  2. From the Package Browser select ExternalInterfaces > Export.


  3. To export to Binary, right-click toBinary in the tree under Export and then select Call Function.
    The ExternalInterfaces.Export.toBinary dialog box is displayed.
  4. In the Model name area of the dialog box:
    1. Click Edit .
      The Select Model dialog box appears.
    2. Select the model you want to export.
    3. Click OK.
    The model name is added to the dialog box.
  5. Optional: In the Export directory you can specify a directory to save the FMU directory, an example might be "E:/Export".

    Notes:

  6. Do one of the following:
    • Click OK: The export function starts and when it has finished the dialog box closes.
    • Click Info: A dialog box is displayed which gives a summary of the export parameters.
    • Click Execute: The export function is started and when it has finished the dialog box remains open.
    • Click Copy Call: The export function and its parameters are copied to the clipboard. You can then paste them into the scripting command window or into a script (.mos) file.
    • Click Close: The export function is dismissed and the dialog box closes.
    if you click OK or Execute:
    • A progress bar appears.
    • The Message Reporting window appears to let you know the export result.
    • If the export is successful, a number of files are created in the selected directory.
    Note: The simulation run-time code added to the exported file dsmodel.c does not contain the most advanced routines from the binary link libraries. It is therefore, for example, not possible to export models with dynamic state selection.

Export by Scripting

You can export a model to Binary using scripting.

Note: Your model is always stored in the default directory when using scripting. See above section for finding out the default directory.

  1. Open the Modelica Scripting window, see Create and Execute a Script.
  2. Use the scripting function translateModel(model) where model is the name of the model that should be exported (including the path to the model, e. g. model="Modelica.Blocks.Examples.PID_Controller").
  3. Execute the script, see the link in step 1.
    When the script is executed:
    • A progress bar appears.
    • The Message Reporting window appears to let you know the export result.
    • If the export is successful, the dymosim.exe and dsin.txt files are created (among other files) in the default directory.
    Note: The simulation run-time code added to the exported file dsmodel.c does not contain the most advanced routines from the binary link libraries. It is therefore, for example, not possible to export models with dynamic state selection.
