This error typically appears during the solver execution phase (warp, cool, or fill analysis). The message often reads: "Error 99998: The disk is full. Cannot write results file."
Network/Firewall Blocks: A firewall might be preventing the solver from communicating with the license server on ports 2080 or 27000-27009. autodesk moldflow error 99998 full
If none of the above work:
| Step | Action | What to look for | |------|--------|------------------| | 1 | Check free disk space on all drives | Less than 20GB free = red flag | | 2 | Check file path length | Count characters from C:\ to .sdy file. Over 200 = risky | | 3 | Verify .mfr file permissions | Right-click > Properties. Uncheck “Read-only” | | 4 | Review the solver log (.out file) | Look for lines with “Allocation failed” or “Buffer overrun” just above 99998 | | 5 | Run a mesh check (Mesh > Mesh Statistics) | Look for zero-volume elements or inverted normals | | 6 | Check Windows Page File settings | Control Panel > System > Advanced > Performance > Advanced > Virtual Memory | This error typically appears during the solver execution
The most common cause. The error says “Full” because your hard drive (or the specific drive where Moldflow writes temporary files) has 0 bytes free. Moldflow requires 5-10x the size of your study file in free space during the solve phase. Over 200 = risky | | 3 | Verify
