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 DMDA

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

Keywords

distributed array, get, processor subset
