Autodesk Moldflow Error 99998 is a generic "unspecified error" that occurs during the analysis stage, typically indicating that the solver has crashed or been terminated by the operating system. Because it is a general catch-all code, troubleshooting requires a systematic look at hardware, software environment, and model integrity. Understanding the Root Causes

Add flow.exe , cool.exe , and warp.exe to your Antivirus/Firewall exceptions. Autodesk Moldflow Error 99998 is a generic "unspecified

If the hardware is sufficient, the issue is often a communication break between the interface and the solver.

Sometimes the project file itself becomes corrupted or points to a path the solver cannot reach.
