feat: Complete Phase 3 - pyNastran Documentation Integration
Phase 3 implements automated OP2 extraction code generation using pyNastran documentation research. This completes the zero-manual-coding pipeline for FEA optimization workflows. Key Features: - PyNastranResearchAgent for automated OP2 code generation - Documentation research via WebFetch integration - 3 core extraction patterns (displacement, stress, force) - Knowledge base architecture for learned patterns - Successfully tested on real OP2 files Phase 2.9 Integration: - Updated HookGenerator with lifecycle hook generation - Added POST_CALCULATION hook point to hooks.py - Created post_calculation/ plugin directory - Generated hooks integrate seamlessly with HookManager New Files: - optimization_engine/pynastran_research_agent.py (600+ lines) - optimization_engine/hook_generator.py (800+ lines) - optimization_engine/inline_code_generator.py - optimization_engine/plugins/post_calculation/ - tests/test_lifecycle_hook_integration.py - docs/SESSION_SUMMARY_PHASE_3.md - docs/SESSION_SUMMARY_PHASE_2_9.md - docs/SESSION_SUMMARY_PHASE_2_8.md - docs/HOOK_ARCHITECTURE.md Modified Files: - README.md - Added Phase 3 completion status - optimization_engine/plugins/hooks.py - Added POST_CALCULATION hook Test Results: - Phase 3 research agent: PASSED - Real OP2 extraction: PASSED (max_disp=0.362mm) - Lifecycle hook integration: PASSED Generated with Claude Code Co-Authored-By: Claude <noreply@anthropic.com>

Post-Processing Hook Generator - Phase 2.9
|
||||
|
||||
Auto-generates middleware Python scripts for post-processing operations in optimization workflows.
|
||||
|
||||
This handles the "post_processing_hooks" from Phase 2.7 LLM analysis.
|
||||
|
||||
Hook scripts sit between optimization steps to:
|
||||
- Calculate custom objective functions
|
||||
- Combine multiple metrics with weights
|
||||
- Apply complex formulas
|
||||
- Transform results for next step
|
||||
|
||||
Examples:
|
||||
- Weighted objective: 0.7 * norm_stress + 0.3 * norm_disp
|
||||
- Custom constraint: max_stress / yield_strength < 1.0
|
||||
- Multi-criteria metric: sqrt(stress^2 + disp^2)

Auto-generates simple Python code for mathematical operations that don't require

This handles the "inline_calculations" from Phase 2.7 LLM analysis.
