Synopsis

#include "petscdmda.h"   
PetscErrorCode DMDASetOffset(DM da, PetscInt xo, PetscInt yo, PetscInt zo, PetscInt Mo, PetscInt No, PetscInt Po)

Collective

Input Parameters

• da - The DMDA

• xo - The offset in the x direction

• yo - The offset in the y direction

• zo - The offset in the z direction

• Mo - The problem offset in the x direction

• No - The problem offset in the y direction

• Po - The problem offset in the z direction

This is used primarily to overlap a computation on a local DMDA with that on a global DMDA without changing boundary conditions or subdomain features that depend upon the global offsets.
