Synopsis

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

Collective on sf

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
