If the problem persists after these steps, contact your IT administrator or Ansys Support and provide the diagnostic file generated in Step 2.
The error "ansyswbu.exe encountered a problem. a diagnostic file has been written" typically indicates a crash in ANSYS Workbench (often during solving, meshing, or startup).
Below is a step‑by‑step diagnostic and resolution plan — not a code script, but a structured procedure you can implement or follow to automatically handle such crashes and extract useful info from the diagnostic file. If the problem persists after these steps, contact
Not just an uninstall—a clean removal:
Why it happens: 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 Outdated or corrupt GPU drivers are one of the leading causes of ansyswbu.exe crashes. Not just an uninstall—a clean removal: Why it
How to identify: Crash occurs when rotating, zooming, or generating mesh previews. Diagnostic file may show OpenGL error or EXCEPTION_ACCESS_VIOLATION with graphics-related stack traces.
Solutions:
This solves the crash instantly for many users:
