The fastest and least intrusive fix involves resetting your local configuration cache. ANSYS automatically recreates these directories with fresh, default settings upon the next startup.

Locate the folder and rename the version subfolder (e.g., rename v232 to v232_old ).

You are using HPC (Distributed Solve) or a job scheduler like PBS or SLURM. The fastest and least intrusive fix involves resetting

How to Fix the "AnsysWBU.exe encountered a problem. A diagnostic file has been written" Error

: Ensure the full file path is shorter than 248 characters . It typically flashes on the screen immediately after

Do not overwrite the same .mechdb file. Every hour, use and add a version number ( Project_v01.wbpj ). ANSYS databases are fragile; rotating them gives you fallbacks.

If the standard fixes fail, use these techniques to investigate further.

When Ansys Workbench (ansyswbuexe) crashes or aborts, it often writes a diagnostic file (log, crash dump, or .log/.diag file). That file records error details (stack trace, module names, environment info) to help identify whether the problem is caused by corrupted project files, licensing, graphics/driver issues, insufficient resources, or a software bug.
