A "bad" mesh is the most common reason for a solver to give up mid-calculation.
I can provide a more targeted fix once I know the you are running.
If the hardware is sufficient, the issue is often a communication break between the interface and the solver. autodesk moldflow error 99998
Elements with an aspect ratio over 50:1 can cause mathematical instability.
Always solve on a local SSD. Solving over a VPN or a shared network drive frequently leads to timeout errors. A "bad" mesh is the most common reason
Export your model as a .udm or .step file and import it into a brand-new project. Summary Checklist for Quick Recovery Restart the Simulation Compute Manager (SCM).
If the error persists after these steps, it is likely a specific related to a unique combination of material data and process settings. To help you get back to your simulation, could you tell me: Which version of Moldflow (2021, 2023, 2024) are you using? Elements with an aspect ratio over 50:1 can
the mesh for intersections or "zero-volume" elements.
Ensure your GPU drivers are current, as Moldflow uses the GPU for certain calculations. Phase 2: Software and Connectivity
