If the diagnostic file persists across fresh models and reduced settings, the problem may be a genuine ANSYS defect. In that case, open a support ticket with ANSYS, Inc. Attach the diagnostic file, the solver output, and a detailed description of your hardware and software versions. ANSYS engineers can run the dump file through a debugger (WinDbg) to pinpoint the exact subroutine that failed. In some cases, they will issue a hotfix or suggest an environment variable to work around the issue (e.g., setting ANSYS_USE_LEGACY_MEMORY_MANAGER=1 ).
To address the error, you can follow these common troubleshooting steps based on community solutions. Quick Fixes
The error is notoriously vague, acting as a catch-all for various internal failures. At its core, ansyswbuexe is the executable responsible for the Mechanical interface. When it fails, it is usually due to a conflict in one of three areas: hardware resources, software compatibility, or corrupted project data. One of the most common culprits is the Graphical Processing Unit (GPU). Because Ansys relies heavily on hardware acceleration to render complex geometries and mesh grids, an outdated driver or an unsupported graphics card can cause the executive to "hang" and terminate, triggering the diagnostic file.
: In Mechanical, navigate to File > Options > Analysis Settings and Solution . Check the Scratch Solver Files Directory and ensure a valid path is selected.
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.
Look for the .dmp or .log file in the directory specified in the error message (usually in your Temp folder or the project directory).
(under Windows Logs > Application). Look for “Application Error” events with ansyswbuexe.exe as the faulting module. The exception code (e.g., 0xc0000005 for access violation) and fault offset can be cross-referenced with ANSYS knowledge base articles.
When the error appears, a log file is generated. Navigate to the following directory to locate it: C:\Users\<YourUsername>\AppData\Roaming\Ansys\vXXX\Workbench\logs\ (Note: vXXX corresponds to your ANSYS version, e.g., v221, v232).
Missing DLLs or a flawed installation.
: If other solutions fail, some users have found success by renaming libiomp5md.dll in C:\Windows\System32 to libiomp5md.dll.old to prevent it from interfering with the version Ansys uses.
Look at the error message for the specific path, or check C:\Users\YourUsername\AppData\Local\Temp .
Open the folder and rename the folder corresponding to your version (e.g., rename v242 to v242.old ).
