Cause: This issue is due to lack of OpenGL drivers, or the old version of OpenGL. It probably happens in the Windows OS that is hosted in a Sandbox environment.
Solution: Install or update the OpenGL drivers to the latest. If it occurs in a sandboxed Windows, install the Mesa for Windows distribution, and deploy the OpenGL software to the application using the included perappdeploy.bat batch file.

Issue 2: Result mesh data dismatching¶

The result contour fails to display due to the dismatched mesh. The error message of this issue is shown in Figure below.

Cause: This issue is due to dismatched data between result and mesh.
Solution: This could be a software defect, send the model to the [email protected] for investigation.
