I can use SpaceClaim from the start menu (its called "scdm" , and its SpaceClaim).
I searched the case and found a similar description, I uninstalled ANSYS 19 and installed the 20 it did not solve (https://studentcommunity.ansys.com/thread/ansys-19-1-geometry-tab-gives-me-the-design-modeler-option-but-not-the-spaceclaim-one/ , I run the cad configuration manager, here the pic of the log file:
I Change the default geometry editor from Design modeler to Spaceclaim (its the opposite to the explanation from the link:https://studentcommunity.ansys.com/thread/how-to-open-designmodeler/):
Please help me find out how to activate the SpaceClaim option like you see I spend a lot of time trying fixing this issue.
Thank you very much!
