Using PyMetis for coloring DOLFIN mesh into partitions

Partitioning of FEniCS meshes by PyMetis

In a nutshell

import dolfin as df
from partitioning import *

mesh = df.UnitSquareMesh(32, 32)
graph = mesh_2_nxgraph(mesh, edge_weight_f=lambda u, v: u+v)

cell_f = partition(graph, 5, weighted=False)
df.File('results/unweighted.pvd') << cell_f

cell_f = partition(graph, 5, weighted=True)
df.File('results/weighted.pvd') << cell_f

Dependencies

• FEniCS 2019.1.+ (python3)
• pymetis

TODO

• Do I need node weights?
