The Intel MPI library conflicts with the Windows network stack or antivirus firewalls.
This error is notorious among engineers using ANSYS Workbench (versions 15.0 through 2024). The message indicates that the core solver executable ( ansyswbuexe.exe ) has crashed unexpectedly. The mention of a “diagnostic file” suggests that ANSYS attempted to save crash logs (usually .dmp or .err files), but more often than not, that file is empty or impossible to decipher without ANSYS customer support. The Intel MPI library conflicts with the Windows
The solver encounters a degenerate Jacobian ratio or zero-volume element, causing a floating-point exception. The mention of a “diagnostic file” suggests that
Remember: The “diagnostic file” is your single biggest clue. Do not delete it immediately. Learn to read its first 20 lines, and you will become the person in your department who actually fixes ANSYS crashes instead of just rebooting and praying. 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. Do not delete it immediately
ANSYS Workbench uses hardware acceleration. Recent NVIDIA/AMD drivers may introduce memory leaks.
