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 topology
- viewer - The - PetscViewerto save data with
- sectiondm - The - DMthat contains the local section on which- vecis defined, can be- NULL
- vec - 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.

       PetscObjectSetName((PetscObject)sectiondm, "sectiondm_name");
       PetscSectionCreate(PETSC_COMM_WORLD, §ion);
       DMPlexGetChart(sectiondm, &pStart, &pEnd);
       PetscSectionSetChart(section, pStart, pEnd);
       PetscSectionSetUp(section);
       DMSetLocalSection(sectiondm, section);
       DMGetLocalVector(sectiondm, &vec);
       PetscObjectSetName((PetscObject)vec, "vec_name");
