New E11 Part Mass Extractor: - Add nx_journals/extract_part_mass_material.py - NX journal using NXOpen.MeasureManager.NewMassProperties() for accurate geometry-based mass - Add optimization_engine/extractors/extract_part_mass_material.py - Python wrapper that reads JSON output from journal - Add E11 entry to extractors/catalog.json Documentation Updates: - SYS_12_EXTRACTOR_LIBRARY.md: Add mass accuracy warning noting pyNastran get_mass_breakdown() under-reports ~7% on hex-dominant meshes with tet/pyramid fill elements. E11 (geometry .prt) should be preferred over E4 (BDF) unless material is overridden at FEM level. - 01_CHEATSHEET.md: Add mass extraction tip V14 Config: - Expand design variable bounds (blank_backface_angle max 4.5°, whiffle_triangle_closeness max 80mm, whiffle_min max 60mm) Testing showed: - E11 from .prt: 97.66 kg (accurate - matches NX GUI) - E4 pyNastran get_mass_breakdown(): 90.73 kg (~7% under-reported) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
