#include "petscdmnetwork.h" PetscErrorCode DMNetworkGetSubnetwork(DM dm,PetscInt netnum,PetscInt *nv,PetscInt *ne,const PetscInt **vtx,const PetscInt **edge)Not collective
dm | - the DM object | |
netnum | - the global index of the subnetwork |
nv | - number of vertices (local) | |
ne | - number of edges (local) | |
vtx | - local vertices of the subnetwork | |
edge | - local edges of the subnetwork |
The local vertices returned on each rank are determined by DMNetwork. The user does not have any control over what vertices are local.
