DMPlexSetIsoperiodicFaceSF

Express periodicity from an existing mesh

Synopsis

#include "petscdmplex.h"   
PetscErrorCode DMPlexSetIsoperiodicFaceSF(DM dm, PetscSF face_sf)

Logically Collective

Input Parameters

• dm - The DMPLEX on which to set periodicity

• face_sf - PetscSF in which roots are (owned) donor faces and leaves are faces that must be matched to a (possibly remote) donor face.

Note

One can use -dm_plex_shape zbox to use this mode of periodicity, wherein the periodic points are distinct both globally and locally, but are paired when creating a global dof space.
