Synopsis

#include "petscdmda.h"   
PetscErrorCode  DMDAGetInfo(DM da,PetscInt *dim,PetscInt *M,PetscInt *N,PetscInt *P,PetscInt *m,PetscInt *n,PetscInt *p,PetscInt *dof,PetscInt *s,DMBoundaryType *bx,DMBoundaryType *by,DMBoundaryType *bz,DMDAStencilType *st)

Input Parameter

da -the distributed array

Output Parameters

dim - dimension of the distributed array (1, 2, or 3)
M, N, P - global dimension in each direction of the array
m, n, p - corresponding number of procs in each dimension
dof - number of degrees of freedom per node
s - stencil width
bx,by,bz - type of ghost nodes at boundary, one of DM_BOUNDARY_NONE, DM_BOUNDARY_GHOSTED, DM_BOUNDARY_MIRROR, DM_BOUNDARY_PERIODIC
st - stencil type, either DMDA_STENCIL_STAR or DMDA_STENCIL_BOX

Note

Use NULL (NULL_INTEGER in Fortran) in place of any output parameter that is not of interest.
