MeshColoring

class dolfin.cpp.mesh.MeshColoring

Bases: object

This class computes colorings for a local mesh. It supports vertex, edge, and facet-based colorings.

static cell_colors(*args) → 'dolfin::CellFunction< std::size_t >'

Overloaded versions

• cell_colors(mesh, coloring_type)

  Return a MeshFunction with the cell colors (used for visualisation)

• cell_colors(mesh, coloring_type)

  Return a MeshFunction with the cell colors (used for visualisation)

static color(mesh: 'Mesh', coloring_type: 'std::vector< std::size_t > const &') → 'std::vector< std::size_t > const &'

Color the cells of a mesh for given coloring type specified by topological dimension, which can be one of 0, 1 or D - 1. Coloring is saved in the mesh topology

static color_cells(mesh: 'Mesh', coloring_type: 'std::string') → 'std::vector< std::size_t > const &'

Color the cells of a mesh for given coloring type, which can be one of “vertex”, “edge” or “facet”. Coloring is saved in the mesh topology

static compute_colors(mesh: 'Mesh', colors: 'std::vector< std::size_t > &', coloring_type: 'std::vector< std::size_t > const &') → 'std::size_t'

Compute cell colors for given coloring type specified by topological dimension, which can be one of 0, 1 or D - 1.
