# DMPlexDistribute
Distributes the mesh and any associated sections. 
## Synopsis
```
#include "petscdmplex.h"   
#include "petscdmlabel.h"  
PetscErrorCode DMPlexDistribute(DM dm, PetscInt overlap, PetscSF *sf, DM *dmParallel)
```
Collective


## Input Parameters

- ***dm  -*** The original `DMPLEX` object
- ***overlap -*** The overlap of partitions, 0 is the default



## Output Parameters

- ***sf -*** The `PetscSF` used for point distribution, or `NULL` if not needed
- ***dmParallel -*** The distributed `DMPLEX` object





## Note
If the mesh was not distributed, the output `dmParallel` will be `NULL`.

The user can control the definition of adjacency for the mesh using `DMSetAdjacency()`. They should choose the combination appropriate for the function
representation on the mesh.
