Autodesk Moldflow Error 99998 Exclusive Link

In the Autodesk Moldflow environment, Error 99998 is a generic "catch-all" execution error. It indicates that the simulation engine (the solver) stopped unexpectedly before completing the task. While it can be caused by mesh issues or connectivity, the "exclusive" variant usually points toward a or hardware resource limitations . Common Causes of Error 99998 1. File Access and Permissions

It was her. The system thought she was currently running the simulation, but the process had crashed silently in the background, leaving the license "dangling." It was a zombie process. The server thought she was still hard at work, locking everyone else out—including herself.

While sounds like a fatal crash, it is almost always a file management or process conflict issue. By clearing your background tasks and ensuring your temporary directories are local and clean, you can resolve the "exclusive lock" and get back to optimizing your parts.
