PETSc version 3.16.6
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 | - 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

Notes
All processors that share the DMDA must call this with the same coordinate value
