Basic Usage Pattern¶

import mmgpy

# Load mesh
mesh = mmgpy.read("input.mesh")

# Configure options
opts = mmgpy.Mmg3DOptions(hmax=0.1)

# Remesh
result = mesh.remesh(opts)

# Validate
report = mesh.validate(detailed=True)

# Save
mesh.save("output.vtk")

Type Hints¶

All public APIs are fully typed. Use with a type-aware IDE for autocomplete:

from mmgpy import Mesh, Mmg3DOptions, RemeshResult

mesh: Mesh = Mesh("input.mesh")
opts: Mmg3DOptions = Mmg3DOptions(hmax=0.1)
result: RemeshResult = mesh.remesh(opts)

Version Information¶

import mmgpy

print(f"mmgpy version: {mmgpy.__version__}")
print(f"MMG version: {mmgpy.MMG_VERSION}")
