PetscSectionCreateGlobalSection

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

Synopsis

#include "petscsection.h"   
PetscErrorCode PetscSectionCreateGlobalSection(PetscSection s, PetscSF sf, PetscBool includeConstraints, PetscBool localOffsets, PetscSection *gsection)

Input Parameters

s - The PetscSection for the local field layout
sf - The SF describing parallel layout of the section points (leaves are unowned local points)
includeConstraints - By default this is PETSC_FALSE, meaning that the global field vector will not possess constrained dofs
localOffsets - If PETSC_TRUE, use local rather than global offsets for 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
