.scdoc File Disapperaing

[turgut.ataseven]

Hi.

While I was setting up mesh, BC etc. of a model and saving the model frequently, after a while I noticed that Geometry line of Static Structural in Workbench had a warning sign. After trying to open the geometry in SpaceClaim, Ansys popped up a warning message implying SYS.scdoc is not found in the directory. When I checked the directory, the .scdoc file was vanished for no reason. Exporting .pmdb geometry from Mechanical and importing that file to the directory with the .scdoc extension did not help. Version is 2023 R2. What caused this problem and what precautions can be taken?
