Several factors can trigger this error, often related to your system's configuration, the specific project you are working on, or the software's interaction with your operating system.
Perform a clean installation to wipe out older, corrupted driver fragments. Force ANSYS to Use the Dedicated GPU
If importing a native CAD file (e.g., SolidWorks, Creo) causes a crash, export the model to a neutral format like STEP or IGES , then import it into SpaceClaim or DesignModeler first. Several factors can trigger this error, often related
ANSYS Mechanical relies heavily on hardware acceleration. Outdated, corrupt, or incompatible graphics drivers (especially when switching between integrated graphics and dedicated GPUs) are the leading cause of this error.
Set the preferred graphics processor to . Switch to Software Graphics Mode (Diagnostic Step) ANSYS Mechanical relies heavily on hardware acceleration
If you suspect your GPU is the issue, you can force ANSYS to use software rendering to test stability:
When AnsysWBU.exe crashes, Windows generates a diagnostic crash dump file—typically named AnsysWBDumpFile.dmp —inside your local %TEMP% directory. While the dump file requires debugging tools like the Windows Debugger to read directly, years of user data point to several primary culprits: Switch to Software Graphics Mode (Diagnostic Step) If
Before diving into complex registry or reinstall procedures, try these high-probability fixes. Clear the Ansys AppData Cache
Corrupted user files are the second most common cause.
