Hi Silvia, 

If you want to run external python scripts from SpaceClaim (IronPython), you first need to download the latest version of Python from the Windows store.
Once it is done, just run the Windows terminal (Windows key + R) and write the command lines I wrote above (pip3 … ). It should work. At least, that is how I did it ( From there, to be able to call an external python script (i.e. a ".py" file) in a SpaceClaim script, you have to write the two lines above (from System.Diagnostics … ).

Unfortunately, I never run numpy in Ansys ACT but I remember finding a video that seemed interesting, judging by the comments :


I hope this helps. Feel free to ask more questions if your problem is still unresolved.
