Ansyswbuexe Encountered A Problem A Diagnostic File Has Been Written New Fixed | REAL × BLUEPRINT |

— Before rerunning, manually delete the project’s .lock and .solve folders. Windows sometimes holds onto files even after a crash.

If you recently updated Windows:

Introduction The ANSYS Workbench executable (ansyswbuexe) is the graphical front end that coordinates project files, launches solvers and tools, and manages the Workbench process. When it crashes or aborts unexpectedly, modern versions present a generic dialog indicating an error and that a diagnostic file was written (often to a temporary or Workbench folder). Because the message is terse, users need a structured approach to diagnose and resolve root causes that range from corrupted user files and license/server issues to GPU/driver conflicts and OS-level permission or antivirus interference. — Before rerunning, manually delete the project’s

4.1 Corrupted project or user settings

: Right-click the Solution or Mesh cell in Workbench and select Clear Generated Data before attempting to reopen the model. When it crashes or aborts unexpectedly, modern versions

Leave a comment with your ANSYS version, the analysis type (static, modal, transient), and the first 5 lines of the .err diagnostic file for a customized solution. : Try clearing generated data by right-clicking on

: Relaunch Ansys Workbench to automatically reconstruct clean directory configurations. 2. Re-route Dedicated Workstation GPU Settings

Fortunately, because this issue has been thoroughly diagnosed across engineering teams, several definitive fixes can restore your environment back to working order. 1. Quick Fix: Clear the User AppData and Temp Profiles

You are using HPC (Distributed Solve) or a job scheduler like PBS or SLURM.
