Running an Ansys Motion-Maxwell Cosimulation on Linux

For users who would like to use the compute power of a Linux machine, an Ansys Motion-Maxwell cosimulation can be set up on a Windows machine, and then executed on a Linux machine. This topic details this procedure.

  1. Install the pyaedt package in the CPython of the ANSYS installation: In a Linux terminal, enter

    <path to ansys_inc>/commonfiles/CPython/3_10/linx64/Release/python/runpython -m pip install pyaedt

  2. On a Windows machine, open the stand-alone version of Anys Motion Preprocessor.
  3. Set up the Motion-Maxwell cosimulation; see Coupling Maxwell with Ansys Motion (Stand-Alone) for more details.
    The Ansys Motion subsystem file (.dfsub file) and the Maxwell project generated by Motion (.aedt file) must be in the same folder.
  4. Export a DFS file for use on Linux: from the Motion Home tab, select Simulation > Run > Export DFS file. It should be exported to the same folder as the Motion and Maxwell files.

  5. Export the DFG file to the same folder as the Motion and Maxwell files: from the Motion Home tab, select Simulation > Run > Export DFG file. This file is necessary to postprocess the solved model on Windows.
  6. Copy the entire folder from the Windows machine to a Linux machine.
  7. On the Linux Machine, cd to the copied folder, and use the rundfs.sh script in the Motion installation folder to run the cosimulation:

    8. <path to ansys_inc>/v242/Motion/solver/rundfs.sh -i Name of dsub file

    There will be a message when the simulation runs to completion:

  8. Copy the entire folder back to the Windows machine for postprocessing.

  9. Open the Ansys Motion Postprocessor to read the solved files in the solved folder:

    The animation will be displayed after opening the .dfr file.
