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
