# DMDAGetLogicalCoordinate
Returns a the i,j,k logical coordinate for the closest mesh point to a `x`, `y`, `z` point in the coordinates of the `DMDA` 
## Synopsis
```
#include "petscdmda.h"   
PetscErrorCode DMDAGetLogicalCoordinate(DM da, PetscScalar x, PetscScalar y, PetscScalar z, PetscInt *II, PetscInt *JJ, PetscInt *KK, PetscScalar *X, PetscScalar *Y, PetscScalar *Z)
```
Collective


## Input Parameters

- ***da -*** the distributed array
- ***x  -*** the first physical coordinate
- ***y  -*** the second physical coordinate
- ***z  -*** the third physical coordinate



## Output Parameters

- ***II -*** the first logical coordinate (-1 on processes that do not contain that point)
- ***JJ -*** the second logical coordinate (-1 on processes that do not contain that point)
- ***KK -*** the third logical coordinate (-1 on processes that do not contain that point)
- ***X  -*** (optional) the first coordinate of the located grid point
- ***Y  -*** (optional) the second coordinate of the located grid point
- ***Z  -*** (optional) the third coordinate of the located grid point





## Note
All processors that share the `DMDA` must call this with the same coordinate value
