Ansyswbuexe Encountered A Problem A Diagnostic File Has Been Written New Patched (UPDATED · SERIES)

A full Windows temporary directory or locked temporary diagnostic files will block ANSYS from writing new computational cache files. Press the to open the Run dialog box. Type %temp% and click OK . Press Ctrl + A to highlight every file in the directory.

The error is a critical crash that completely shuts down the ANSYS Workbench Mechanical interface. It occurs when the simulation environment fails to initialize graphics, access system memory, or read specific project geometry files.

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.

Find the folder named (note the period prefix) and rename it to .ansys.old . Relaunch Ansys Workbench to see if the issue persists. 2. Update Graphics Card Drivers

— Open it in a text editor. Search for “ExceptionCode” (Windows) or “SIGSEGV” (Linux). If you see 0xc0000005 (Access Violation), suspect memory corruption. 0xc00000fd means stack overflow — check for deeply nested APDL commands or UMATs. AI responses may include mistakes

Ansys Mechanical relies heavily on hardware acceleration to render geometry, mesh models, and post-processed result contours. If your workstation uses an integrated Intel processor alongside a dedicated GPU (NVIDIA/AMD), the system may default to the weak integrated chip, causing AnsysWBU.exe to crash.
