If you are reading this, you have likely been interrupted by a pop-up window that no ANSYS Mechanical user wants to see: “ansyswbuexe encountered a problem and needed to close. A diagnostic file has been written (new).” You have probably lost hours of simulation time, and the frustration is palpable. Certain advanced settings can crash the solver reliably
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
The error message is one of the most common and frustrating generic crash errors in Ansys Workbench. It typically triggers when opening Ansys Mechanical, DesignModeler, or the Meshing module , forcing the program to close and generating a .dmp (memory dump) file in your local temporary directory.
