V2022, ANSYS CFX-Pre (black screen)

    • jpabraham

      My university just upgraded to 2022 and when running a CFX analysis, when I open CFE-Pre the graphics screen is black.  No problems with spaceclaim, or with the mesher.  Just at CFX-Pre.  Any ideas?

      Are you working on the local system or on a remote desktop? 

      In the latter case, try setting an environment variable on the remote system. 

      • Name: QT_OPENGL
      • Value: desktop 


      You will find an ocean of resources on the internet on how to set an environment variable.
