Autodesk Moldflow Error 99998

Error 99998 in Autodesk Moldflow typically indicates a critical solver or convergence failure during simulation. It’s a general, non-specific error code that often arises when the solver cannot progress due to model, mesh, boundary condition, or numerical setup problems. Common root causes:

Verify that your computer meets the minimum system requirements for running Autodesk Moldflow. This includes having a compatible operating system, sufficient RAM, and a capable graphics card.

Error 99998 is a non-specific failure code usually raised when the solver encounters a problem it can’t recover from. It often points to one of these underlying issues: autodesk moldflow error 99998

If the issue persists after trying the above steps, it may be beneficial to contact Autodesk Support directly. They can provide:

In the hierarchy of Moldflow’s error handling, code 99998 is a catch-all system-level failure. It indicates that the Moldflow solver process (typically mfs_solver.exe or similar) was terminated unexpectedly, and the software could not categorize the reason into a standard engineering error (mesh quality, process settings) or a licensing error (e.g., Error 15). Error 99998 in Autodesk Moldflow typically indicates a

Think of it as a "segmentation fault" in Unix or an "Access Violation" in Windows. The solver tried to read or write to a memory address it didn’t have permission to access, or an external process killed it. Therefore, Error 99998 is rarely a "mesh problem" – it is an environment, data handling, or resource problem.

A tier-one automotive supplier was running a warp analysis on a 2.5 million element 3D dashboard bezel (ABS/PC). Every run failed at 87% of the "Pack" stage with Error 99998. The mesh statistics were excellent (avg aspect ratio 5.2, no negative Jacobians). They can provide: In the hierarchy of Moldflow’s

Diagnosis: The IT department had recently deployed Symantec Endpoint Protection. The log showed Symantec was scanning C:\Users\moldflow_user\AppData\Local\Temp\moldflow_4567.mfr exactly at the moment of failure.

Solution: The engineering workstation was moved to an antivirus exclusion group for all .mfr, .m3r, and .mda file types. The analysis completed successfully in 4 hours, and warpage predictions matched physical scan data within 0.3 mm.
