- Create introspect_sim.py NX journal to extract solutions, BCs from SIM files
- Update introspect_sim_file() to optionally call NX journal for full introspection
- Add FEM mesh section (nodes, elements, materials, properties) to IntrospectionPanel
- Add SIM solutions and boundary conditions sections to IntrospectionPanel
- Show introspection method and NX errors in panel
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)

Major Features Added:
1. Centralized Configuration System (config.py)
- Single source of truth for all NX and environment paths
- Change NX version in ONE place: NX_VERSION = "2412"
- Change Python environment in ONE place: PYTHON_ENV_NAME = "atomizer"
- Automatic path derivation and validation
- Helper functions: get_nx_journal_command()
- Future-proof: Easy to upgrade when NX 2506+ released
2. NX Path Corrections (Critical Fix)
- Fixed all incorrect Simcenter3D_2412 references to NX2412
- Updated nx_updater.py to use config.NX_RUN_JOURNAL
- Updated dashboard/api/app.py to use config.NX_RUN_JOURNAL
- Corrected material library path to NX2412/UGII/materials
- All files now use correct NX2412 installation
3. NX Expression Import System
- Dual-method expression gathering (.exp export + binary parsing)
- Robust handling of all NX expression types
- Support for formulas, units, and dependencies
- Documented in docs/NX_EXPRESSION_IMPORT_SYSTEM.md
4. Study Management & Analysis Tools
- StudyCreator: Unified interface for study/substudy creation
- BenchmarkingSubstudy: Automated baseline analysis
- ComprehensiveResultsAnalyzer: Multi-result extraction from .op2
- Expression extractor generator (LLM-powered)
5. 50-Trial Beam Optimization Complete
- Full optimization results documented
- Best design: 23.1% improvement over baseline
- Comprehensive analysis with plots and insights
- Results in studies/simple_beam_optimization/
Documentation Updates:
- docs/SYSTEM_CONFIGURATION.md - System paths and validation
- docs/QUICK_CONFIG_REFERENCE.md - Quick config change guide
- docs/NX_EXPRESSION_IMPORT_SYSTEM.md - Expression import details
- docs/OPTIMIZATION_WORKFLOW.md - Complete workflow guide
- Updated README.md with NX2412 paths
Files Modified:
- config.py (NEW) - Central configuration system
- optimization_engine/nx_updater.py - Now uses config
- dashboard/api/app.py - Now uses config
- optimization_engine/study_creator.py - Enhanced features
- optimization_engine/benchmarking_substudy.py - New analyzer
- optimization_engine/comprehensive_results_analyzer.py - Multi-result extraction
- optimization_engine/result_extractors/generated/extract_expression.py - Generated extractor
Cleanup:
- Removed all temporary test files
- Removed migration scripts (no longer needed)
- Clean production-ready codebase
Strategic Impact:
- Configuration maintenance time: reduced from hours to seconds
- Path consistency: 100% enforced across codebase
- Future NX upgrades: Edit ONE variable in config.py
- Foundation for Phase 3.2 Integration completion
