DMNetworkSetEdgeList

Sets the list of local edges (vertex connectivity) for the network

Synopsis

#include "petscdmnetwork.h"  
PetscErrorCode DMNetworkSetEdgeList(DM dm,PetscInt *edgelist[],PetscInt *edgelistCouple[])
Logically collective on DM

Input Parameters

dm - the dm object
edgelist - list of edges for each subnetwork
edgelistCouple - list of edges for each coupling subnetwork

Notes

There is no copy involved in this operation, only the pointer is referenced. The edgelist should not be destroyed before the call to DMNetworkLayoutSetUp

Example usage

Consider the following 2 separate networks and a coupling network

 network 0: v0 -> v1 -> v2 -> v3
 network 1: v1 -> v2 -> v0
 coupling network: network 1: v2 -> network 0: v0

The resulting input edgelist[0] = [0 1 | 1 2 | 2 3]; edgelist[1] = [1 2 | 2 0] edgelistCouple[0] = [(network)1 (v)2 (network)0 (v)0].
