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].
