Exporting data to LS-DYNA from the user interface

Note: This feature is only available on Windows systems.

The Autodesk Moldflow Insight to LS-DYNA interface requires the following:

  • A Midplane meshed model.
  • Results of a Fill+Pack + Warp analysis sequence, with Fiber results if a fiber-filled material is selected.
    Note: Set the desired LS-DYNA interface options before launching the analysis.
  • A license to use the LS-DYNA Interface.

There are two parts to exporting Autodesk Moldflow Insight data for input to LS-DYNA: running the mpi2dyn.vbs macro to create the necessary files, and locating the files and using them in LS-DYNA.

To run the mpi2dyn.vbs macro from the user interface:

  1. Click Play Macro (Tools tab > Automation panel > Play Macro).
  2. In the Open Macro dialog, navigate to the location where the mpi2dyn.vbs file is stored. By default, this location is C:\Program Files\Autodesk\Moldflow Synergy 20xx\data\commands, where xxxx is the version number of the Autodesk Moldflow Insight software you are using.
  3. Click on the mpi2dyn.vbs script, and then click Open. The script plays.

The API script saves the interface files in a folder created within the current project folder. For example, My Documents\My AMI 20xx Projects\Project1\<study_name>_interface_files, where xxxx is the software release number and <study_name> is the name of the study you are exporting to LS-DYNA.

Once the files are in that location, you can use them in LS-DYNA. Refer to your LS-DYNA manual or help system for instructions on how to import them and perform the LS-DYNA analysis.
