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).

Invalid characters in file paths are a very common cause of this crash. Ensure all directories involved (installation folder, project folder, geometry import/export folder) contain only . Avoid spaces and special characters (e.g., Chinese, Cyrillic, Arabic). When the error appears, a log file is generated

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. For example, enabling “Large Deflection” on a model

The auto-detection of initial contact gap leads to a numerical singularity in the stiffness matrix. Ensure all directories involved (installation folder
