DMNetworkSetSizes

Sets the number of subnetworks, local and global vertices and edges for each subnetwork.

Synopsis

#include "petscdmnetwork.h"  
PetscErrorCode DMNetworkSetSizes(DM dm,PetscInt Nsubnet,PetscInt NsubnetCouple,PetscInt nV[], PetscInt nE[], PetscInt NV[], PetscInt NE[])
Collective on DM

Input Parameters

dm - the dm object
Nsubnet - number of subnetworks
NsubnetCouple - number of coupling subnetworks
nV - number of local vertices for each subnetwork and coupling subnetwork
nE - number of local edges for each subnetwork and coupling subnetwork
NV - number of global vertices (or PETSC_DETERMINE) for each subnetwork and coupling subnetwork
NE - number of global edges (or PETSC_DETERMINE) for each subnetwork and coupling subnetwork

Notes If one processor calls this with NV (NE) of PETSC_DECIDE then all processors must, otherwise the prgram will hang.

You cannot change the sizes once they have been set. nV, nE, NV and NE are arrays of length Nsubnet+NsubnetCouple.
