Exporting data to LS-DYNA from the command line

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 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 command line:

Note: The command line will look for scripts stored in the default directory, typically My Documents\My AMI 20XX Projects\commands. If no script is found, it will look in C:\Program Files\Autodesk\Moldflow Synergy 20XX\data\commands, where xxxx is the software release number.

  1. Click (View tab > Windows panel > User Interface) and then select Command Line.

  2. Enter mpi2dyn.

  3. Click Go. 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 ** 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.
