Autodesk Moldflow Error 99998

Review your injection time, packing pressure, and melt temperatures.

For most users, this is the first and most effective solution. Autodesk provides a dedicated License Configuration utility that simplifies the process of pointing Moldflow to the correct license server.

Ensure the workstation time matches the license server time. Also, verify that ports 27000 through 27009 (and any specifically designated port) are open through any active firewalls. Conclusion

Always run simulations on local solid-state drives. Running analyses across network shared drives or cloud-synced folders (like OneDrive or Dropbox) causes micro-disconnects that trigger Error 99998. autodesk moldflow error 99998

Zoom into the injection node to ensure it rests on a clean, connected surface mesh. Reassign the injection location precisely to a valid node.

It tells you that your simulated molding process is physically unstable. Instead of forcing the solver, treat it like a real molding problem:

Set the dropdown level to match your entitlement precisely (e.g., ). Review your injection time, packing pressure, and melt

Moldflow relies heavily on temporary scratch files. If these files become corrupted, the solver will immediately reject the simulation run. Close Autodesk Moldflow Synergy.

Users often find that separate installations for the UI and solver can cause confusion.

This method is particularly useful when the Insight solvers are configured to look at a different license server than Synergy. Ensure the workstation time matches the license server time

Adopting these proactive strategies can help you avoid this error in the future:
