Pipeline Architecture
Parameters (D, L, U)
│
┌──────▼──────────────────────────────────────────────────────┐
│ Stage 1: Gmsh mesh generation │
│ stub_gmsh.py OR gmsh Python API │
│ Output: work_dir/mesh.msh │
└──────┬───────────────────────────────────────────────────────┘
│ mesh.msh
┌──────▼──────────────────────────────────────────────────────┐
│ Gate 1: Mesh quality check │
│ validate_mesh_quality.py │
│ Checks: max_skewness < 4.0, non-orthog < 70°, cells > 100 │
│ FAIL → abort with structured report │
└──────┬───────────────────────────────────────────────────────┘
│ pass
┌──────▼──────────────────────────────────────────────────────┐
│ Converter 1: Gmsh .msh → OpenFOAM polyMesh │
│ convert_gmsh_to_openfoam.py │
│ Uses: gmshToFoam CLI (preferred) or meshio (fallback) │
│ Stub mode: skipped (stub solver writes its own output) │
└──────┬───────────────────────────────────────────────────────┘
│ constant/polyMesh/
┌──────▼──────────────────────────────────────────────────────┐
│ Stage 3: OpenFOAM CFD simulation │
│ stub_openfoam.py OR simpleFoam │
│ Output: log.simpleFoam + postProcessing/forces/0/force.dat │
└──────┬───────────────────────────────────────────────────────┘
│ force.dat
┌──────▼──────────────────────────────────────────────────────┐
│ Gate 2: CFD convergence + force balance │
│ validate_cfd_convergence.py │
│ Checks: all residuals < 1e-4, force balance error < 5% │
│ FAIL → abort with residual log │
└──────┬───────────────────────────────────────────────────────┘
│ pass
┌──────▼──────────────────────────────────────────────────────┐
│ Converter 2: OpenFOAM forces → OrcaFlex load CSV │
│ convert_openfoam_to_orcaflex.py │
│ Output: loads.csv (Time, Fx, Fy, Fz, Mx, My, Mz) │
└──────┬───────────────────────────────────────────────────────┘
│ loads.csv
┌──────▼──────────────────────────────────────────────────────┐
│ Stage 5: OrcaFlex structural/mooring analysis │
│ stub_orcaflex.py OR OrcFxAPI │
│ Output: max_deflection_m, max_tension_N │
└──────┬───────────────────────────────────────────────────────┘
│
pipeline_results.json (PASS / FAIL per gate + final metrics)
