Detailed Description

This module contains various classes and functions to interface with the Metis grid partitioning library.

The most important and convenient class in this module is MetisPartitioning.

Function Documentation

template<class GRID>
void write_metis_cell_graph (  GRID const &    G,
std::ostream &    out
) 
 

Write a grid in Metis graph format, where cells correspond to graph nodes and facets to graph edges.

Template parameters:
  • GRID:
    • type grid_types<GRID> gt;
    • type gt::Cell;
    • type gt::Facet;
    • type gt::CellIterator;
    • type gt::CellOnCellIterator;
    • type grid_function<Cell,int>;

Definition at line 10 of file grid-to-metis.C.

template<class GRID, class FACETFCT>
void write_metis_cell_graph_edge_weights (  GRID const &    G,
FACETFCT const &    weights,
std::ostream &    out
) 
 

Write a grid in Metis graph format, where cells correspond to graph nodes and facets to graph edges.

This function also writes weights on edges.

Template parameters:
In addition to write_metis_cell_graph:
  • FACETFCT:
    • value_type operator()(gt::Facet)
    • value_type convertible to int
    • weights(F) is an integer > 0

Definition at line 46 of file grid-to-metis.C.

template<class GRID>
int write_metis_mesh (  GRID const &    G,
std::ostream &    out
) 
 

Write a grid in Metis mesh format.

G must consist entirely of triangles OR entirely of quads. Else use write_metis_graph.

Template parameters:
  • type grid_types<GRID> gt;
  • type gt::Cell
  • type gt::CellIterator
  • type gt::Facet
  • type gt::CellOnCellIterator;

Definition at line 83 of file grid-to-metis.C.
