Geodels / meshplex

Compute Voronoi tesselations and everything else you need.

meshplex

Compute Voronoi tesselations and everything else you need for finite-volume discretizations. Do it fast, too.

Usage

Given a triangular or tetrahedral mesh, meshplex computes

• covolumes,
• control volumes,
• cell circumcenters,
• the surface areas,
• control volume circumcenters,

and much more.

To use meshplex, simple read a mesh (e.g., this pacman):

mesh = meshplex.read('pacman.msh')

print(mesh.node_coords)
print(mesh.control_volumes)

mesh.show()

(For mesh creation, check out pygmsh, mshr, pygalmesh, meshzoo, optimesh or any other tool.)

Installation
