ansys.post_processing.plot_nodal_temperature() throws error when changing the ansys directory to the current python directory

ps1. On a different topic, after I updated the library to the current version, no files are created when I run a simulation, so pyansys.read_binary(‘file.rst’) doesn’t work, as no rst file is created.

MAPDL will always create files, but with the latest version it’s going to save the files to a temporary directory for each ANSYS run. Get the directory MAPDL is running in with print(ansys.directory).

I changed the directory to the current python directory, it was storing everything in my temp local appdata, but now I get the following message when I use:

ansys.post_processing.plot_nodal_temperature(window_size=[1920, 1880], cpos='iso', screenshot = str(I)+'A_thermal_iso.png', off_screen=True, stitle='Temperature (deg Celsius)')

Could you help me fix it?

I renamed the file Python_projects, and it worked for the 40,000 element mesh (4 pixels), but for the 320,000 (8 pixels) element mesh, it didn’t. I get the same pic as the one I attached last time. I cannot understand this behavior.
