The diagnostic file is intended to help, but in practice, it often frustrates more than it assists.
— Extract the solver input file ( .dat or .inp ) and run ansysXXXX.exe -b -i input.dat -o output.out . This isolates whether the problem is in Workbench UI or the solver itself.
The "Ansyswbuexe encountered a problem a diagnostic file has been written new" error can be frustrating, but by understanding its causes and following the troubleshooting steps outlined in this article, you should be able to resolve the issue and get back to working with ANSYS. If you're still experiencing problems, consider reaching out to ANSYS support or a qualified engineer for further assistance. The diagnostic file is intended to help, but
Mechanical and Meshing environments rely heavily on hardware acceleration. Outdated or incompatible GPU drivers frequently trigger .dmp crashes.
The crash happens at the same simulation step (e.g., writing the sparse matrix). Your system RAM is high (16GB+) but the error persists. The "Ansyswbuexe encountered a problem a diagnostic file
Locate the folder and rename the version subfolder (e.g., rename v232 to v232_old ).
Large FEA models (especially nonlinear contact, explicit dynamics, or coupled-field analyses) can cause the ansyswbuexe process to exceed the available RAM or virtual memory. Windows will terminate the process without mercy, and ANSYS catches this as “encountered a problem.” Outdated or incompatible GPU drivers frequently trigger
4.6 Insufficient memory, corrupted swap/pagefile, or system instability
When you see “ansyswbuexe encountered a problem a diagnostic file has been written new” , follow this checklist:
Sometimes, a pending Windows update or a missing .NET Framework library causes instability. Ensure your Windows OS is fully updated.
