When I load the pyansys script in qt creator, it crashes directly after mapdl enters the preparation phase.

The following figure proves that I correctly called the Python script through a sub thread and obtained the output result. However, when I am about to use pyANSYS, every time the initialization code below runs, there will also be a mapdl pop-up window, and then the program will crash directly. Does anyone know why this is happening???

If you could discuss with me, thank you very much for your help！

mapdl = launch_mapdl() mapdl.clear() mapdl.prep7()

Are you able to use launch_mapdl in a normal script?

If so, when in your qt script, PyMAPDL is trying to start, you should see an error if it cannot. What error is this one?

Do you have any other MAPDL instances running?

If this does not help, you might need to share a minimum working example (MWE) so I can have a look.

Any update on this @COOLEST-GET ?
