Create a section describing the global field layout using the local section and an SF describing the section point overlap.

Synopsis

#include "petscdmlabel.h"   
#include "petscis.h"        
PetscErrorCode PetscSectionCreateGlobalSectionLabel(PetscSection s, PetscSF sf, PetscBool includeConstraints, DMLabel label, PetscInt labelValue, PetscSection *gsection)

Input Parameters

+ s - The PetscSection for the local field layout . sf - The SF describing parallel layout of the section points . includeConstraints - By default this is PETSC_FALSE, meaning that the global field vector will not possess constrained dofs . label - The label specifying the points - labelValue - The label stratum specifying the points

Output Parameter

. gsection - The PetscSection for the global field layout

Note: This gives negative sizes and offsets to points not owned by this process
