DMPlexCSRAlgorithm

The algorithm for building the adjacency graph in CSR format, usually for a mesh partitioner

Synopsis

typedef enum {
  DM_PLEX_CSR_MAT,
  DM_PLEX_CSR_GRAPH,
  DM_PLEX_CSR_OVERLAP
} DMPlexCSRAlgorithm;

Values

• DM_PLEX_CSR_MAT - Use MatPartitioning by first making a matrix

• DM_PLEX_CSR_GRAPH - Use the original DMPLEX and communicate along the boundary

• DM_PLEX_CSR_OVERLAP - Build an overlapped DMPLEX and then locally compute
