Ansyswbuexe Encountered A Problem A Diagnostic File Has Been Written New Jun 2026

From ANSYS 12.0 to the latest 202x releases, this exact string (“ansyswbuexe encountered a problem...”) has remained nearly unchanged. Why?

The error occurs when the executable ( ansyswbu.exe ) crashes. The "diagnostic file" ( AnsysWBDumpFile.dmp ) is a technical log intended for developers to debug the code, though it is rarely useful for end-users. Top 5 Solutions to Fix the Crash 1.

A single inverted element, a zero-thickness layer, or a degenerated contact surface can cause the solver to perform an illegal mathematical operation. For example, a Jacobian determinant approaching zero in an element will cause the stiffness matrix to become singular. The solver does not gracefully exit; it crashes. Solution: Use the “Mesh Metric” tools to check for skewness and orthogonal quality. Run a “Geometry Check” in DesignModeler. Simplify or defeature problematic regions.
