#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 (that is the number of grid points) 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. The sum of these entries must equal M |
-dm_view | - Calls DMView() at the conclusion of DMDACreate1d() | |
-da_grid_x <nx> | - number of grid points in x direction | |
-da_refine_x <rx> | - refinement factor | |
-da_refine <n> | - refine the DMDA n times before creating it |
You must call DMSetUp() after this call before using this DM.
If you wish to use the options database to change values in the DMDA call DMSetFromOptions() after this call but before DMSetUp().
