Corrupted settings in the AppData folder are the most frequent cause. Resetting them forces Ansys to create clean default files. SimuTech Group AnsysWBU.exe encountered a problem
Note: Only do this if the file exists in System32; do not delete it from Ansys installation folders. Ansys Innovation Space Step 4: Additional Troubleshooting Corrupted settings in the AppData folder are the
Certain advanced settings can crash the solver reliably. For example, enabling “Large Deflection” on a model with poorly constrained degrees of freedom may cause the solver to iterate to infinity. Using a direct solver (e.g., Sparse) on a model with billions of degrees of freedom will exhaust memory faster than an iterative solver. Requesting unrealistic time steps in a transient analysis can also lead to numerical overflow. Solution: Simplify the analysis first. Start with linear, static, small-deflection assumptions. Gradually add complexity while saving intermediate results. Requesting unrealistic time steps in a transient analysis
Open the folder and rename the folder corresponding to your version (e.g., rename v242 to v242.old ). Corrupted settings in the AppData folder are the
The error is a generic crash message indicating that the Workbench/Mechanical executable (AnsysWBU.exe) has failed and generated a memory dump ( .dmp ) file. This file is typically located in your %TEMP% folder (e.g., C:\Users\username\AppData\Local\Temp\AnsysWBDumpFile.dmp ) and is intended for software developers to debug the specific crash.
