Core Capabilities (+4)

Core Capabilities

• CAD Automation: Script-based FreeCAD operations
• Batch Processing: Parallel file processing with pattern matching
• Parametric Design: Design tables and parameter variations
• Assembly Management: Constraint solving and assembly creation
• FEM Preprocessing: Mesh generation and boundary conditions
• Drawing Generation: Automatic dimensioning and views
• Natural Language Processing: Convert commands to CAD operations
• Script Generation: Auto-generate Python scripts from prompts

Marine Engineering Specialization

• Hull NURBS generation from HullProfile stations (scipy fallback without FreeCAD)
• Hydrostatic analysis: displaced volume, waterplane area, KB, BM via section integration
• Stability calculations
• Mooring system configuration
• Structural analysis preprocessing

FEM Analysis (v2.0)

• CalculiX INP file generation from gmsh mesh data
• FRD/DAT result parsing (displacements, von Mises stress)
• End-to-end FEM chain: geometry → mesh → solve → extract
• Plate-with-hole Kt validation (Kt ≈ 3.0)

Design Table Studies (v2.0)

• YAML-driven parametric sweeps (cartesian product of parameters)
• Process-level parallelism via multiprocessing (FreeCAD not thread-safe)
• Comparison YAML output for all variations
• Manifold validation: watertight check, self-intersection, normal consistency

Integration Points

• OrcaFlex: Data exchange for hydrodynamic analysis
• AQWA: Diffraction analysis geometry
• Signal Analysis: Module connectivity
• REST API: External system integration
