# Unit Conversion Traps (+3) ## Unit Conversion Traps | Source | Mass Unit | Inertia Unit | Density | Convert to spec.yml | |--------|-----------|-------------|---------|---------------------| | WAMIT `.frc` | te | te·m² | 1 (te/m³) | ×1000 for kg, kg·m² | | OrcaWave | te | te·m² | 1 (te/m³) | ×1000 for kg, kg·m² | | AQWA | kg | kg·m² | 1025 (kg/m³) | Direct | | spec.yml | kg | kg·m² | kg/m³ | — | **Trap**: When porting from WAMIT `.frc` to spec.yml, multiply inertia by 1000 (te·m² → kg·m²). Do NOT multiply twice — the ISSC TLP case 2.5 had a 1000x error from double conversion. ## Phase Correlation for Zero-Magnitude DOFs Fixed DOFs (e.g. heave/roll/pitch on TLPs) produce zero RAO magnitudes. Phase is undefined (`atan2(0,0)` noise), so: - `multi_solver_comparator.py`: overrides phase correlation to 1.0 when `peak_mag < 1e-10` - `validate_owd_vs_spec.py`: skips DOFs with `max_diff < 1e-6` in pass/fail verdict ## Benchmark Report Geometry Schematics The `build_mesh_schematic_html()` in `benchmark_plotter.py` renders interactive 3D Plotly mesh visualizations. It requires `mesh_path` in `solver_metadata`. When using `build_orcawave_metadata_from_yml()`, propagate `mesh_path` from `build_solver_metadata()` base metadata — the enriched YAML metadata doesn't resolve mesh paths. ## Mesh Quality Assessment - **Adjacent panel ratio** (between neighbors) is the key metric — not global min/max area ratio - Gradual size variation is acceptable even with large global ratio - Report uses `NOTE:` prefix (informational) not `WARNING:` for area ratio - Advanced metrics (Jacobian, aspect ratio, skewness) available via gmsh meshing tool
