Ansyswbuexe Encountered A Problem A Diagnostic File Has Been Written New < 100% SIMPLE >

The error is a critical crash that completely shuts down the ANSYS Workbench Mechanical interface. It occurs when the simulation environment fails to initialize graphics, access system memory, or read specific project geometry files.

: Outdated or conflicting dynamic link libraries left behind by legacy third-party CAD applications can interfere with proper operations.

If you are on a laptop, ensure Windows is set to use your "High-performance NVIDIA processor" for Ansys, rather than the integrated Intel/AMD chip. 3. Review the Diagnostic File

Please contact support and provide the diagnostic file for further analysis. You may need to restart the application. If the issue persists, try repairing the installation or checking for available updates.

Check if your antivirus has quarantined any files in the Ansys installation folder. Add an exclusion for C:\Program Files\ANSYS Inc . 5. Re-registering .NET Framework

— ANSYS Mechanical relies heavily on your GPU for rendering. An outdated or incompatible graphics driver is among the most commonly cited triggers for the error. One user reported that updating their preferred graphics driver to the latest version resolved the crash.

One of the most common reasons behind this crash is a corrupted project file. A corrupted model can cause Workbench to fail when trying to read or process data. Similarly, a damaged ANSYS installation—perhaps incomplete, missing files, or with registry errors—is a frequent culprit. In several reported cases, a fresh Windows installation or reinstalling the entire ANSYS suite was necessary to resolve the issue.
