Install

# Cadquery dependency install seperately since for some systems conda install is necessary
# Please view https://github.com/CadQuery/cadquery if install doesn't work for your system
conda install -c conda-forge -c cadquery cadquery=master

pip install git+https://github.com/OpenOrion/meshql.git#egg=meshql

Example

See more examples in examples directory

Cube

import cadquery as cq
import numpy as np
from meshql import GeometryQL
from meshql.utils.shapes import generate_naca4_airfoil

# Create a simple CAD model
airfoil_coords = generate_naca4_airfoil("0012", num_points=40) * 5 - np.array([2.5,0])

with GeometryQL() as geo:
    geo = (
        geo
        .load(
            cq.Workplane("XY")
            .box(10,10,10)
            .faces(">Z")
            .workplane(centerOption="CenterOfMass")
            .polyline(airfoil_coords) # type: ignore
            .close()
            .cutThruAll()
        )

        .faces(type="interior")
        .addPhysicalGroup("wing")
        .addBoundaryLayer(
            size=0.001,
            ratio=1.5,
            num_layers=3,
        )
        .end()

        .generate(2)
        .show("mesh")

    )
