Ensure your material data sheet is fully populated. Missing specific heat or thermal conductivity values over certain temperature ranges can cause mathematical exceptions in the solver code. Preventing Future Crashes Verify Server Status : Use the LMTools Utility

Real-time scanning software (McAfee, Symantec, Sophos, or even Windows Defender) often views the Moldflow solver’s behavior as suspicious. The solver writes temporary binary files ( .mfr , .m3r , .mda ) to the temp directory at high speed. An aggressive antivirus may lock these files for scanning, causing a write conflict. The software fails gracefully? No. It dies with Error 99998.
