Create a section describing the global field layout using the local section and an SF describing the section point overlap.
Synopsis
#include "petscvec.h"
PetscErrorCode PetscSectionCreateGlobalSectionCensored(PetscSection s, PetscSF sf, PetscBool includeConstraints, PetscInt numExcludes, const PetscInt excludes[], PetscSection *gsection)
Input Parameters
+ s - The PetscSection for the local field layout Many br. sf - The SF describing parallel layout of the section points Many br. includeConstraints - By default this is PETSC_FALSE, meaning that the global field vector will not possess constrained dofs Many br. numExcludes - The number of exclusion ranges Many br- excludes - An array [start_0, end_0, start_1, end_1, ...] where there are numExcludes pairs Many br
Output Parameter
. gsection - The PetscSection for the global field layout Many br
Note: This gives negative sizes and offsets to points not owned by this process Many br
