MeshCreateLocalCSR

Returns the local mesh in CSR format. All off processor edges are ignored, and only the symmetric part of the matrix is stored if symmetric is true.

Synopsis

#include "mesh.h" 
int MeshCreateLocalCSR(Mesh mesh, int *numVertices, int *numEdges, int **vertOffsets, int **vertNeighbors,
                       double **vertCoords, int numBC, int *bcNodes, PetscTruth symmetric)

Not collective

Input Parameters

	mesh	- The mesh
	numBC	- [Optional] The number of constrained nodes to be eliminated
	bcNodes	- [Optional] The numbers of constrained nodes
	symmetric	- Whether to return the entire adjacency list

Output Parameters

	numVertices	- The number of vertices in the graph
	numEdges	- The number of edges in the graph.
	vertOffsets	- The list of offsets into the neighbor array for each vertex
	vertNeighbors	- The list of vertex neighbors
	vertCoords	- The list of vertex coordinates

Note

If any array, such as vertCoords, is passed as PETSC_NULL, then no return value will be calculated.
