# 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, 3] and vertices = [4, 6]. The new orderings will be specific to the subset (i.e vertices = [0, 2]).

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

### Level
