#include "petscmat.h" PetscErrorCode MatMeshToVertexGraph(Mat mesh,PetscInt ncommonnodes,Mat *dual)Collective on Mat
|mesh||- the graph that represents the mesh|
|ncommonnodes||- mesh elements that share this number of common nodes are considered neighbors, use 2 for triangules and quadralaterials, 3 for tetrahedrals and 4 for hexahedrals|
The columns of each row of the Mat mesh are the global vertex numbers of the vertices of that rows cell. The number of rows in mesh is number of cells, the number of columns is the number of vertices.
