DMLoad#

Loads a DM that has been stored in binary with DMView().

Synopsis#

#include "petscdm.h"          
#include "petscdmlabel.h"     
#include "petscds.h"     
PetscErrorCode DMLoad(DM newdm, PetscViewer viewer)

Collective

Input Parameters#

Notes#

The type is determined by the data in the file, any type set into the DM before this call is ignored.

Using PETSCVIEWERHDF5 type with PETSC_VIEWER_HDF5_PETSC format, one can save multiple DMPLEX meshes in a single HDF5 file. This in turn requires one to name the DMPLEX object with PetscObjectSetName() before saving it with DMView() and before loading it with DMLoad() for identification of the mesh object.
