# DMNetworkAssembleGraphStructures

Assembles vertex and edge data structures. Must be called after DMNetworkDistribute.

### Synopsis

    #include "petscdmnetwork.h"
    PetscErrorCode DMNetworkAssembleGraphStructures(DM dm)

Collective

### Input Parameters

| dm | - The DMNetworkObject

### Note: the routine will create alternative orderings for the vertices and edges. Assume global network points are

points = [0 1 2 3 4 5 6]

where edges = [0,1,2,3] and vertices = [4,5,6]. The new orderings will be specific to the subset (i.e vertices = [0,1,2] <- [4,5,6]).

With this new ordering a local PetscSection, global PetscSection and PetscSF will be created specific to the subset.
