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
