PetscSectionGetValueLayout#
Get the PetscLayout associated with the section dofs of a PetscSection
Synopsis#
#include "petscsection.h"
PetscErrorCode PetscSectionGetValueLayout(MPI_Comm comm, PetscSection s, PetscLayout *layout)
Collective
Input Parameters#
comm - The
MPI_Comms - The
PetscSection
Output Parameter#
layout - The dof layout for the section
Notes#
PetscSectionGetPointLayout() provides similar information but only counting the number of points with nonzero degrees of freedom and
including the constrained degrees of freedom
This is usually called for the default global section.
Example#
The chart is [2,5), point 2 has 4 dof (2 constrained), point 3 has 0 dof, point 4 has 1 dof (not constrained)
The local size of the `PetscLayout` is 3 since there are 3 unconstrained degrees of freedom on this MPI process
