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 on da
Input Parameters
|  | da | - the distributed array | 
|  | x,y,z | - the physical coordinates | 
Output Parameters
|  | II, JJ, KK | - the logical coordinate (-1 on processes that do not contain that point) | 
|  | X, Y, Z, | - (optional) the coordinates of the located grid point | 
Notes
All processors that share the DMDA must call this with the same coordinate value
