Hello Olivier,

You should be able to open a simple square surface. Try to set all settings back to default by doing the following:


  1. Close all WB.
  2. Type %appdata% in Windows file explorer and press enter.
  3. Go in the Ansys folder and rename the v231 folder to v231_old.
  4. Restart WB. This will reset WB to default settings.


If this doesn't hep, I would try to uninstall and reinstall WB 2023R1. 

Is this the student version or the commercial version?
