Troubleshooting¶

If you encounter an issue that cannot be resolved here, please send the project file (*.wsdb and the associated folder) to info@welsim.com for investigation.

Issue 1: No graphical window (No OpenGL driver)¶

The graphics window fails to display items, or no any windows show up.

finite_element_analysis_welsim_troubleshooting_opengl2

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.

finite_element_analysis_welsim_result_data_point_error1

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.

Issue 3: Excessive solving time for explicit transient structrual analysis¶

When using OpenRadioss as the solver for transient structural problems, the solving time is significantly longer than expected. * Cause: When the material density is too small, it can lead to very small time steps, which in turn causes the solving time to be excessively long.

Solution: Check the material density value, and increase the value if it is incorrect.
