Gets information about a given distributed array.
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)
Not Collective
Input Parameter#
da - the
DMDA
Output Parameters#
dim - dimension of the
DMDA(1, 2, or 3)M - global dimension in first direction of the array
N - global dimension in second direction of the array
P - global dimension in third direction of the array
m - corresponding number of MPI processes in first dimension
n - corresponding number of MPI processes in second dimension
p - corresponding number of MPI processes in third dimension
dof - number of degrees of freedom per node
s - stencil width

by - type of ghost nodes at boundary in second dimension
bz - type of ghost nodes at boundary in third dimension
st - stencil type, either
DMDA_STENCIL_STARorDMDA_STENCIL_BOX
Note#
Use NULL (PETSC_NULL_INTEGER in Fortran) in place of any output parameter that is not of interest.
