• Test on another computer – Isolates hardware or OS issues.
• Reduce model scale – Simulate only a representative section (e.g., a 1 mm slice of a thick part).
• Contact Autodesk Support – Provide the solver log (*.out or *.log file from the study directory). Look for lines near the end just before "FATAL ERROR."
