Look in your _ProjectName_files folder under dp0\SYS\MECH .

This isolates whether the problem is within a specific project or the application itself: Look in your _ProjectName_files folder under dp0\SYS\MECH

Workbench uses OpenGL for rendering 3D models in Mechanical, Meshing, and DesignModeler. Outdated or corrupt GPU drivers are one of the leading causes of ansyswbu.exe crashes. Look in your _ProjectName_files folder under dp0\SYS\MECH

Download the latest "Enterprise" or "Studio" drivers (rather than Game Ready drivers) for your GPU. Look in your _ProjectName_files folder under dp0\SYS\MECH

If you encounter this error repeatedly despite following the steps above, consider evaluating your workstation specifications against ANSYS’s hardware requirements, and ensure you are running a certified graphics driver configuration. Simulation stability begins with a stable foundation.

If the crash persists, some Windows prerequisites (like C++ Redistributables or .NET Framework) might be broken.
