While the error log might occasionally include terms like "full," it is rarely a disk space issue; instead, it typically means the license pool is full (all seats are in use) or the solver cannot reach the server. Common Causes & Fixes

Incorrect License Configuration: The Simulation Compute Manager (SCM) or the solver might be looking at the wrong license server.

Moldflow uses a default temp folder on your C: drive. If C: is a small SSD, it will fill up quickly.

Solution:

  2. Type: mfsu -temp "D:\Moldflow_Temp" (change D: to a large, fast drive).
  3. Press Enter.
  4. Also set this in Moldflow > Tools > Application Options > File Locations > Temporary Files.

Solution 2: Repair or Reinstall Autodesk Moldflow

  1. Try repairing the Autodesk Moldflow installation using the Control Panel (Windows) or the Applications folder (macOS).
  2. If repairing doesn't work, uninstall and reinstall Autodesk Moldflow.

  2. Rename your study to something short, like Run1.
  3. Ensure no spaces or special characters (except underscores) are in the path.
  4. Re-run the analysis. This alone solves 30% of Error 99998 cases.
