Reset the SCM. Stop the Autodesk Simulation Compute Manager service in Windows Services. Navigate to C:\ProgramData\Autodesk\SCM\vX\data (where X is the version number) and clear the temporary database files, then restart the service. Network and Temporary Drive Space

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

Autodesk Moldflow Error 99998 can be frustrating, but it is highly solvable with systematic troubleshooting. In over 90% of cases, the issue is resolved by properly configuring the license settings, ensuring version compatibility, or performing a clean reinstallation. By following the steps outlined in this guide, you can identify the root cause and restore normal operation with minimal downtime. If all troubleshooting steps fail, contact Autodesk Support directly with your analysis log and system information for further assistance.

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).

Run a mesh statistics check. Use the Mesh Repair Wizard to identify and fix elements exceeding an aspect ratio of 50:1 for Dual Domain, or 100:1 for 3D meshes. Overlapping Elements and Free Edges

When all else fails, a complete clean reinstallation is necessary.

Troubleshooting Autodesk Moldflow Error 99998: License and Solver Issues Reset the SCM

Most instances of Error 99998 stem from three primary categories: mesh quality, hardware limitations, or software/license conflicts. 1. Mesh Defects and Geometric Issues

A compromised or overly complex mesh can cause the mathematical solver to encounter singularities, leading to an immediate crash. High Aspect Ratio Elements

Large 3D meshes with millions of elements can easily exhaust system memory.
