Check that (or higher) is enabled in "Windows Features." 4. Hardware Acceleration & Workspace Reset The "ansyswbuexe encountered a problem a diagnostic file

The error “ansyswbuexe encountered a problem and a diagnostic file has been written” is a frustrating but informative failure. It tells you that the solver process terminated not due to user input error, but due to a fundamental violation of operating system or mathematical constraints. The diagnostic file, though opaque to most, is a key that can unlock the cause—if you know where to look and how to interpret the context. The diagnostic file, though opaque to most, is

If the diagnostic file persists across fresh models and reduced settings, the problem may be a genuine ANSYS defect. In that case, open a support ticket with ANSYS, Inc. Attach the diagnostic file, the solver output, and a detailed description of your hardware and software versions. ANSYS engineers can run the dump file through a debugger (WinDbg) to pinpoint the exact subroutine that failed. In some cases, they will issue a hotfix or suggest an environment variable to work around the issue (e.g., setting ANSYS_USE_LEGACY_MEMORY_MANAGER=1 ). Attach the diagnostic file, the solver output, and

A common fix is to reset ANSYS Workbench's user-specific settings and caches. This will not delete your saved projects:

Ensure your scratch directory (where Ansys writes temporary math files) has plenty of GBs available. If the drive fills up mid-process, the executable will hang and crash.

Some aggressive Anti-Virus (AV) programs flag the communication between Workbench and its solvers as suspicious activity.
