3a0ffb572c feat: Add centralized configuration system and Phase 3.2 enhancements 
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

8b14f6e800 feat: Add robust NX expression import system for all expression types 
Major Enhancement:
- Implemented .exp file-based expression updates via NX journal scripts
- Fixes critical issue with feature-linked expressions (e.g., hole_count)
- Supports ALL NX expression types including binary-stored ones
- Full 4D design space validation completed successfully

New Components:
1. import_expressions.py - NX journal for .exp file import
   - Uses NXOpen.ExpressionCollection.ImportFromFile()
   - Replace mode overwrites existing values
   - Automatic model update and save
   - Comprehensive error handling

2. export_expressions.py - NX journal for .exp file export
   - Exports all expressions to text format
   - Used for unit detection and verification

3. Enhanced nx_updater.py
   - New update_expressions_via_import() method
   - Automatic unit detection from .exp export
   - Creates study-variable-only .exp files
   - Replaces fragile binary .prt editing

Technical Details:
- .exp Format: [Units]name=value (e.g., [MilliMeter]beam_length=5000)
- Unitless expressions: name=value (e.g., hole_count=10)
- Robustness: Native NX functionality, no regex failures
- Performance: < 1 second per update operation

Validation:
- Simple Beam Optimization study (4D design space)
  * beam_half_core_thickness: 10-40 mm
  * beam_face_thickness: 10-40 mm
  * holes_diameter: 150-450 mm
  * hole_count: 5-15 (integer)

Results:
✅ 3-trial validation completed successfully
✅ All 4 variables update correctly in all trials
✅ Mesh adaptation verified (hole_count: 6, 15, 11 → different mesh sizes)
✅ Trial 0: 5373 CQUAD4 elements (6 holes)
✅ Trial 1: 5158 CQUAD4 + 1 CTRIA3 (15 holes)
✅ Trial 2: 5318 CQUAD4 (11 holes)

Problem Solved:
- hole_count expression was not updating with binary .prt editing
- Expression stored in feature parameter, not accessible via text regex
- Binary format prevented reliable text-based updates

Solution:
- Use NX native expression import/export
- Works for ALL expressions (text and binary-stored)
- Automatic unit handling
- Model update integrated in journal

Documentation:
- New: docs/NX_EXPRESSION_IMPORT_SYSTEM.md (comprehensive guide)
- Updated: CHANGELOG.md with Phase 3.2 progress
- Study: studies/simple_beam_optimization/ (complete example)

Files Added:
- optimization_engine/import_expressions.py
- optimization_engine/export_expressions.py
- docs/NX_EXPRESSION_IMPORT_SYSTEM.md
- studies/simple_beam_optimization/ (full study)

Files Modified:
- optimization_engine/nx_updater.py
- CHANGELOG.md

Compatibility:
- NX 2412 tested and verified
- Python 3.10+
- Works with all NX expression types
