# DMGetCellCoordinateDM
Gets the `DM` that prescribes cellwise coordinate layout and scatters between global and local cellwise coordinates 
## Synopsis
```
#include "petscdm.h"          
PetscErrorCode DMGetCellCoordinateDM(DM dm, DM *cdm)
```

## Input Parameter

- ***dm -*** the `DM`



## Output Parameter

- ***cdm -*** cellwise coordinate `DM`, or NULL if they are not defined





## Note
Call `DMLocalizeCoordinates()` to automatically create cellwise coordinates for periodic geometries.
