Ansyswbuexe Encountered A Problem A Diagnostic File Has Been Written New [updated]

Because it is a generic fatal error, the underlying cause ranges from corrupt project profile settings to hardware driver mismatches. This guide details the most common root causes and outlines systematic steps to resolve the issue. Common Root Causes

ANSYS often names it ansyswbuexe.exe.[timestamp].dmp . If multiple dump files exist with identical timestamps, the crash may be multi-threaded (a race condition). If only one exists, it is likely a deterministic bug.

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.
