DistMeshPy

DistMeshPy is a Python implementation of the DistMesh algorithm based on the original MATLAB implementation.

Features

• Generate 2D, 3D, and surface meshes with a simple interface.
• Flexible distance functions for custom geometries.
• Robust mesh size control through a size function.
• Backend utility compiled via C++ code.

Installation

pip install distmeshpy

Note: A working C++11 order higher compiler is required.

Usage

Here's a quick example of how to generate a 2D mesh:

from distmeshpy import distmesh2d
from distmeshpy.utils import dcircle, huniform

p, t = distmesh2d(
    lambda p: dcircle(p, 0.0, 0.0, 1.0),  # Distance function
    huniform,  # Uniform size function
    0.2,  # Initial edge size
    ((-1.1, 1.1), (-1.1, 1.1)),  # Bounding box
)

and the mesh can be plotted via matplotlib:

import matplotlib.pyplot as plt
fig, ax = plt.subplots()
ax.triplot(p[:, 0], p[:, 1], t)
ax.set_aspect("equal")
plt.show()
