DMDAGetOwnershipRanges

Gets the ranges of indices in the x, y and z direction that are owned by each process

Synopsis

#include "petscdmda.h"   
PetscErrorCode  DMDAGetOwnershipRanges(DM da,const PetscInt *lx[],const PetscInt *ly[],const PetscInt *lz[])
Not Collective

Input Parameter

da - the DMDA object

Output Parameter

lx - ownership along x direction (optional)
ly - ownership along y direction (optional)
lz - ownership along z direction (optional)

Level: intermediate

Note: these correspond to the optional final arguments passed to DMDACreate(), DMDACreate2d(), DMDACreate3d()

In Fortran one must pass in arrays lx, ly, and lz that are long enough to hold the values; the sixth, seventh and eighth arguments from DMDAGetInfo()

In C you should not free these arrays, nor change the values in them. They will only have valid values while the DMDA they came from still exists (has not been destroyed).

These numbers are NOT multiplied by the number of dof per node.
