Confirm that ports 20030 and 2080 are open for communication between the workstation and the server. 3. Inspect Geometry and Mesh Quality
Ensure you have a stable VPN or LAN connection if using a network license. autodesk moldflow error 99998 best
If the error occurs during the "Filling" stage, try slightly increasing the global edge length to see if a coarser mesh bypasses the crash. 4. Update Software and Drivers Confirm that ports 20030 and 2080 are open
Re-import the .udm file. This often strips away hidden corruption in the original project database. If the error occurs during the "Filling" stage,
Delete files in your %TEMP% folder to ensure the solver has enough "scratch" space.
Are you running the simulation ? Did this model mesh successfully before you hit solve?
Autodesk Moldflow Error 99998 is a generic "unexpected failure" message that typically indicates the solver has crashed due to memory limitations, licensing interruptions, or problematic geometry. Because it is a catch-all error, the "best" way to fix it involves a systematic process of elimination.
