Hello,
You should not need to add the SUFC option manually - you can set this in Workbench from the time domain Analysis Settings, under Common Analysis Options:
You also need to start the Python server before the time domain analysis is launched. You can do this using a pre-solve Python script, or you can do it manually from the Windows command line. You can find an example of the Python server code in the Ansys installation, at C:\Program Files\ANSYS Inc\v232\aqwa\utils\ExternalForceCalculation\AqwaServerMgr.py (change the 'v232' as necessary for your installed version). You should not need to modify the code in AqwaServerMgr.py.
I hope this helps!
Mike
