CGFoil

CGFoil is a CGAL-based airfoil meshing tool for generating constrained Delaunay triangulations of airfoils with plies and webs.

Installation

Install with uv:

uv pip install .

Usage

CLI help

Generate mesh from YAML:

cgfoil mesh examples/airfoil_mesh.yaml -o mesh.pkl

Plot existing mesh:

cgfoil plot mesh.pkl -f plot.png -s

Export to VTK:

cgfoil export vtk mesh.pkl -o output.vtk

Export to ANBA:

cgfoil export anba mesh.pkl -o output.json

Run with defaults:

cgfoil run -p -v output.vtk -f naca0018.dat -s

Options:

• -p, --plot: Plot the triangulation
• -v, --vtk FILE: Output VTK file
• -f, --file FILE: Path to airfoil data file (.dat), default: naca0018.dat
• -s, --split: Enable split view plotting
• --plot-file FILE: Save plot to file

Examples

See the examples/ directory for programmatic usage, including loading from YAML.
