vamseeachanta 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
