# DMView
Views a `DM`. Depending on the `PetscViewer` and its `PetscViewerFormat` it may print some ASCII information about the `DM` to the screen or a file or save the `DM` in a binary file to be loaded later or create a visualization of the `DM` 
## Synopsis
```
#include "petscdm.h"          
#include "petscdmlabel.h"     
#include "petscds.h"     
PetscErrorCode DMView(DM dm, PetscViewer v)
```
Collective


## Input Parameters

- ***dm -*** the `DM` object to view
- ***v -*** the viewer





## Notes
Using `PETSCVIEWERHDF5` type with `PETSC_VIEWER_HDF5_PETSC` as the `PetscViewerFormat` one can save multiple `DMPLEX`
meshes in a single HDF5 file. This in turn requires one to name the `DMPLEX` object with `PetscObjectSetName()`
before saving it with `DMView()` and before loading it with `DMLoad()` for identification of the mesh object.
