PetscSectionCreateGlobalSectionLabel#

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

Synopsis#

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

Collective

Input Parameters#

s - The PetscSection for the local field layout
sf - The PetscSF 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
