Summary:
- Temperature extraction: Ready for thermal OP2 files (SOL 153/159)
- Thermal gradient: Ready (approximation based on temperature range)
- Heat flux: Ready for thermal OP2 files
- Modal mass: Ready for modal F06 files (SOL 103)

Note: Full testing requires thermal and modal analysis result files.
The extractors will return appropriate error messages for non-thermal/modal data.
