DMCreate#
Creates an empty DM
object. DM
s are the abstract objects in PETSc that mediate between meshes and discretizations and the algebraic solvers, time integrators, and optimization algorithms.
Synopsis#
#include "petscdm.h"
#include "petscdmlabel.h"
#include "petscds.h"
PetscErrorCode DMCreate(MPI_Comm comm, DM *dm)
Collective
Input Parameter#
comm - The communicator for the
DM
object
Output Parameter#
dm - The
DM
object
Notes#
See DMType
for a brief summary of available DM
.
The type must then be set with DMSetType()
. If you never call DMSetType()
it will generate an
error when you try to use the dm.
