Orcawave Mesh Generation
When to Use
- Converting CAD geometry (STL, OBJ, STEP) to OrcaWave panel mesh
- Generating GDF (Geometry Definition File) for OrcaWave
- Running mesh convergence studies
- Validating mesh quality (watertight, normals, aspect ratio)
- Optimizing waterline panel refinement
- Checking symmetry and enforcing port/starboard symmetry
- Preparing multi-body meshes with proper separation
Python API
Basic Mesh Generation
from digitalmodel.orcawave.mesh import OrcaWaveMeshGenerator
# Initialize generator
generator = OrcaWaveMeshGenerator()
# Load CAD geometry
generator.load_geometry("geometry/hull.stl")
# Generate panel mesh
*See sub-skills for full details.*
### Mesh Convergence Study
```python
from digitalmodel.orcawave.mesh_study import MeshConvergenceStudy
# Initialize study
study = MeshConvergenceStudy()
# Define mesh sizes to test
mesh_configs = [
{"target_panels": 500, "label": "coarse"},
{"target_panels": 1000, "label": "medium"},
*See sub-skills for full details.*
### STL to GDF Conversion
```python
from digitalmodel.orcawave.converters import STLtoGDFConverter
# Initialize converter
converter = STLtoGDFConverter()
# Convert with options
converter.convert(
input_file="geometry/hull.stl",
output_file="geometry/hull.gdf",
*See sub-skills for full details.*
### Waterline Refinement
```python
from digitalmodel.orcawave.mesh import WaterlineRefiner
# Initialize refiner
refiner = WaterlineRefiner()
# Load existing mesh
refiner.load_mesh("geometry/hull_coarse.gdf")
# Apply waterline refinement
*See sub-skills for full details.*
