DMPlexLocalVectorView#
Saves a local vector
Synopsis#
#include "petscdmplex.h"
PetscErrorCode DMPlexLocalVectorView(DM dm, PetscViewer viewer, DM sectiondm, Vec vec)
Collective
Input Parameters#
dm - The
DMthat represents the topologyviewer - The
PetscViewerto save data withsectiondm - The
DMthat contains the local section on whichvecis defined, can beNULLvec - The local vector to be saved
Note#
In general dm and sectiondm are two different objects, the former carrying the topology and the latter carrying the section, and have been given a topology name and a section name, respectively, with PetscObjectSetName(). In practice, however, they can be the same object (or in case sectiondm is NULL) if it carries both topology and section; in that case the name of the object is used as both the topology name and the section name.
