Autodesk Moldflow Error 99998 is a common but vague runtime error that can interrupt simulation workflows and frustrate engineers. This post explains likely causes, step-by-step troubleshooting, and practical fixes to get your simulations running again.
Before attempting fixes, you must identify the source. Based on analysis from Autodesk forums and support tickets, these are the most common triggers:
to test different variables, the software may hit a "hidden" parallel solve limit. The Symptom:
Excessively high element counts or extreme mesh distortions. autodesk moldflow error 99998
Communication lags can trigger this error even if the license exists.
Ensure the license installed actually covers the module you are running (e.g., AMI_STANDARD, AMI_ADVANCED, or AMA_ULTIMATE).
If you are using an options file to manage license usage, check if a specific user or machine is blocked, or if a user has checked out all available seats. 5. Verify License Product Level
Error 99998 rarely has one cause. It’s a , and the roots are usually a mix of: Go to the Advanced tab and click under Virtual Memory

Verify if all licenses are currently checked out by other users.
If the error persists after the basic steps, use these advanced techniques.
When Moldflow exhausts physical RAM, it switches to the Windows paging file. If this file is too small or restricted, the solver crashes instantly with Error 99998. Before attempting fixes, you must identify the source

Under Process Settings > Advanced Solver Parameters , she changed:
Always solve on a local SSD. Solving over a VPN or a shared network drive frequently leads to timeout errors.
For solvers running on Linux, the environment variables must point correctly to the Autodesk Licensing Service:
