The simulation exceeded available system RAM, causing a memory overflow.
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. Do not overwrite the same
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.
From ANSYS 12.0 to the latest 202x releases, this exact string (“ansyswbuexe encountered a problem...”) has remained nearly unchanged. Why?

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.
