#include "petscdmda.h" PetscErrorCode DMDASetRefinementFactor(DM da, PetscInt refine_x, PetscInt refine_y,PetscInt refine_z)Logically Collective on DMDA
| da | - the DMDA object | |
| refine_x | - ratio of fine grid to coarse in x direction (2 by default) | |
| refine_y | - ratio of fine grid to coarse in y direction (2 by default) | |
| refine_z | - ratio of fine grid to coarse in z direction (2 by default) |
| -da_refine_x | - refinement ratio in x direction | |
| -da_refine_y | - refinement ratio in y direction | |
| -da_refine_z | - refinement ratio in z direction |
