ANSYSWBUEXE encountered a problem. A diagnostic file has been written. If this error occurs weekly: Relaunch Ansys Workbench
Do not overwrite the same .mechdb file. Every hour, use and add a version number ( Project_v01.wbpj ). ANSYS databases are fragile; rotating them gives you fallbacks.
If you have a laptop, ensure Ansys is set to use the dedicated GPU rather than integrated graphics via the NVIDIA Control Panel Manage 3D Settings Ansys Innovation Space 3. Set the Scratch Solver Directory Do not overwrite the same
ANSYS Workbench relies heavily on hardware acceleration. If your GPU drivers are outdated or if you are using an integrated chip instead of a dedicated NVIDIA/AMD card, ansyswbuexe may fail.
When confronted with the error, resist the urge to immediately restart or reinstall. Instead, follow a disciplined process: If you have a laptop, ensure Ansys is
The simulation giveth, and the simulation taketh away. Blessed be the name of the diagnostic file.
If you are working in ANSYS Workbench and suddenly see the message you know how frustrating it can be. This generic error often strikes right as you’re about to solve a complex simulation or save your project, effectively halting your workflow.

ANSYS often names it ansyswbuexe.exe.[timestamp].dmp . If multiple dump files exist with identical timestamps, the crash may be multi-threaded (a race condition). If only one exists, it is likely a deterministic bug.
