#include "petscdmda.h" PetscErrorCode DMDACreate1d(MPI_Comm comm, DMBoundaryType bx, PetscInt M, PetscInt dof, PetscInt s, const PetscInt lx[], DM *da)Collective on MPI_Comm
| comm | - MPI communicator | |
| bx | - type of ghost cells at the boundary the array should have, if any. Use DM_BOUNDARY_NONE, DM_BOUNDARY_GHOSTED, or DM_BOUNDARY_PERIODIC. | |
| M | - global dimension of the array (use -M to indicate that it may be set to a different value from the command line with -da_grid_x <M>) | |
| dof | - number of degrees of freedom per node | |
| s | - stencil width | |
| lx | - array containing number of nodes in the X direction on each processor, or NULL. If non-null, must be of length as the number of processes in the MPI_Comm. |
| -dm_view | - Calls DMView() at the conclusion of DMDACreate1d() | |
| -da_grid_x <nx> | - number of grid points in x direction; can set if M < 0 | |
| -da_refine_x <rx> | - refinement factor | |
| -da_refine <n> | - refine the DMDA n times before creating it, if M < 0 |
