It was 2:00 AM on a Tuesday, and the coffee in the breakroom had long since turned into a sludge resembling the amorphous polymer Eduardo was trying to simulate.
The hardware acceleration clashed with the Moldflow Synergy interface or solver threads. Step-by-Step Troubleshooting Guide
Add flow.exe , cool.exe , and warp.exe to your Antivirus/Firewall exceptions.

Identifying the root cause requires systematic troubleshooting. The most frequent culprits include: It was 2:00 AM on a Tuesday, and
Previous simulation data in the temporary directory is blocking the solver.
Open (or run mlc.exe from the bin folder).
Autodesk Moldflow Error 99998 is a generic solver failure message. It indicates that the simulation engine crashed or terminated unexpectedly before completing the analysis. Because it acts as a catch-all error, troubleshooting requires systematic isolation of the root cause. The most frequent culprits include: Previous simulation data
Error 99998 is a generic solver exit code. Unlike errors 1000–5000, which point to specific modeling or material issues, 99998 signals that the solver encountered an unhandled exception—often due to system resources, file corruption, or mesh anomalies. It can occur in Fill, Pack, Warp, or Cool analyses.
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
Autodesk Moldflow Error 99998 is a licensing error that indicates the software cannot find or access the required solver license (Insight) to run an analysis
[Error 99998 Occurs] │ ▼ 1. Check Log Files ───► Look for preceding errors (e.g., "Out of Memory", "Isolated Node") │ ▼ 2. Check Storage ─────► Verify local scratch drive has >50GB free space │ ▼ 3. Run Mesh Diagnostics ► Fix high aspect ratios, free edges, and overlapping elements │ ▼ 4. Simplify Process ──► Run a basic "Fill" analysis only. If successful, the issue lies in Packing, Cooling, or Warp settings.
