Identifying which part of the simulation fails helps narrow down material or mesh issues.
For recent versions, Autodesk provides a dedicated utility to manage these settings. Close all Moldflow instances.

The triggers for this error generally fall into three categories: mesh corruption, hardware limitations, or software/licensing conflicts. 1. Mesh Defects and High Aspect Ratios The most common trigger is poor mesh quality.
If you are a plastics engineer or a mold designer, few things are as frustrating as an interrupted analysis. You’ve spent hours meshing a complex part, setting up injection locations, and defining process parameters—only to be greeted by the dreaded .
Remember: When you see 99998, think “file system,” not “mesh quality.” 97%… 98%… 99%… Identifying which part of the
The error indicates that all available licenses for the requested product level ( AMI_STANDARD , AMI_PREMIUM , or AMI_ULTIMATE ) may be in use. If using a token-based license, the analysis may require more tokens than available. For certain analysis types, Error 99998 can be accompanied by ("Required license for fiber is not available" or similar), reinforcing the diagnosis of missing or incorrectly configured features.
When simulating massive 3D models with millions of elements, your hardware may run out of physical memory.
Overlapping elements, micro-edges, unstitched surfaces, or severe aspect ratio distortions in the mesh. Attempt to replace the license server hostname with
She clicked . Nothing. She Googled it. Three results — two in Korean, one dead link. Error 99998 was the ghost of the moldflow world. No documentation. No clear cause. Just a black hole where her weekend used to be.
Sometimes the GUI-based job manager fails, but the standalone solver works.
Open the analysis text log before looking at the model. Scroll to the very bottom of the log. Look at the last successfully completed iteration. The lines immediately preceding the "Error 99998" message often indicate if the crash happened during the filling, packing, or cooling phase, narrowing down your search. Step 2: Repair the Mesh
Before attempting fixes, you must identify the source. Based on analysis from Autodesk forums and support tickets, these are the most common triggers:
