- solve_simulation.py: FEM finder now excludes idealized parts, falls back to loading .fem
- solve_simulation.py: hole_count written as [Constant] not [MilliMeter] in .exp
- run_doe.py: dual logging to console + results/doe_run.log
Complete the NXOpenSolver class in nx_interface.py with production-ready
evaluate() and close() methods, following proven patterns from
M1_Mirror/SAT3_Trajectory_V7.
Pipeline per trial:
1. NXSolver.create_iteration_folder() — HEEDS-style isolation with fresh
model copies + params.exp generation
2. NXSolver.run_simulation() — journal-based solve via run_journal.exe
(handles expression import, geometry rebuild, FEM update, SOL 101)
3. extract_displacement() — max displacement from OP2
4. extract_solid_stress() — max von Mises with auto-detect element type
(tries all solid types first, falls back to CQUAD4 shell)
5. extract_mass_from_expression() — reads _temp_mass.txt from journal,
with _temp_part_properties.json fallback
Key decisions:
- Auto-detect element type for stress (element_type=None) instead of
hardcoding CQUAD4 — the beam model may use solid or shell elements
- Lazy solver init on first evaluate() call for clean error handling
- OP2 fallback path: tries solver result first, then expected naming
convention (beam_sim1-solution_1.op2)
- Mass fallback: _temp_mass.txt -> _temp_part_properties.json
- LAC-compliant close(): only uses session_manager.cleanup_stale_locks(),
never kills NX processes directly
Expression mapping (confirmed from binary introspection):
- beam_half_core_thickness, beam_face_thickness, holes_diameter, hole_count
- Mass output: p173 (body_property147.mass, kg)
Refs: OP_09, OPTIMIZATION_STRATEGY.md §8.2
- Use optimization_engine.nx.updater.NXParameterUpdater for expression updates (.exp import method)
- Use optimization_engine.nx.solver.NXSolver for journal-based solving (run_journal.exe)
- Use optimization_engine.extractors for displacement, stress, and mass extraction
- Displacement: extract_displacement() from pyNastran OP2
- Stress: extract_solid_stress() with cquad4 support (shell elements), kPa→MPa conversion
- Mass: extract_mass_from_expression() reads from temp file written by solve journal
- Support for iteration folders (HEEDS-style clean state between trials)
- Proper error handling with TrialResult(success=False, error_message=...)
- 600s timeout per trial (matching existing NXSolver default)
- Keep stub solver and create_solver() factory working
- Maintain run_doe.py interface compatibility

Generates publication-ready PSD figures from OP2 FEA data:
- psd_multi_angle.png: PSD curves for all elevation angles
- psd_band_decomposition.png: LSF/MSF/HSF bar chart
- psd_40deg_composite.png: WFE surface + PSD side-by-side
- psd_trajectory.png: Band evolution vs elevation
Uses Atomizer's full OPD pipeline for consistency with CDR WFE numbers.
- tools/wfe_psd.py: Quick PSD computation for WFE surfaces
- optimization_engine/insights/wfe_psd.py: Full PSD module with band
decomposition (LSF/MSF/HSF), radial averaging, Hann windowing,
and visualization support
- knowledge_base/lac/session_insights/stopp_command_20260129.jsonl:
Session insight from stopp command implementation
PSD analysis decomposes WFE into spatial frequency bands per Tony Hull's
JWST methodology. Used for CDR V7 to validate that MSF (support
print-through) dominates the residual WFE at 85-89% of total RMS.
- X-axis now auto-ranges from data (was going to 10^21)
- Band annotations clamped to actual data extent
- Legend moved to upper-right (was overlapping data)
- Thicker lines (2.5px), larger axis labels
- dtick=1 for clean log-scale tick marks
- Band RMS now uses direct Parseval: sqrt(sum(|FFT|²) / N⁴ / hann_power)
- Previous approach had dimensional mismatch (cycles/apt vs cycles/mm)
- Results now match Zernike filtered RMS within ~10%:
40° vs 20°: PSD=6.18nm vs Zernike=7.70nm
60° vs 20°: PSD=15.83nm vs Zernike=17.69nm
90° Abs: PSD=27.01nm vs Zernike=22.33nm
- PSD plot curve uses separate normalization (shape, not absolute)
- Refactored compute_surface_psd to return dict with freqs, psd, bands
- Remove compute_spatial_freq_metrics() and _spatial_freq_html()
- Add compute_surface_psd(): 2D FFT + Hann window + radial averaging
- Add compute_psd_band_rms(): gravity/support/HF band decomposition
- Add make_psd_plot(): interactive log-log PSD plot with band annotations
- Add _psd_summary_html(): band RMS cards with % breakdown
- New section in report: Power Spectral Density Analysis
- Zernike details now show only coefficient bar charts (cleaner)
- Methodology: Tony Hull JWST approach for WFE spatial frequency analysis
New tool: tools/generate_optical_report.py
- CDR-ready single HTML report from OP2 results
- Executive summary with pass/fail vs targets
- Per-angle WFE analysis with 3D surface plots
- Zernike trajectory analysis (mode-specific RMS)
- Axial vs lateral sensitivity matrix
- Manufacturing correction metrics
- Collapsible Zernike coefficient bar charts
- Optional study DB integration for design params
- Annular aperture support (default M1 inner R=135.75mm)
- Dark theme, interactive Plotly charts, print-friendly
- Replace brittle order-based subcase mapping with name-based search
- Tools now directly search for required angles (20, 40, 60, 90) by label
- Ignores extra subcases (e.g., 30, 50 degrees) without errors
- Falls back to numeric IDs (1,2,3,4) if angle labels not found
- Clear error messages show exactly which subcases are missing
This allows running WFE analysis on simulations with >4 subcases
without manual file/code modifications.
