PetscSectionGetFieldConstraintIndices

Get the field dof numbers, in [0, fdof), which are constrained

Synopsis

#include "petscsection.h"   
PetscErrorCode PetscSectionGetFieldConstraintIndices(PetscSection s, PetscInt point, PetscInt field, const PetscInt **indices)
Not collective

Input Parameters

s - The PetscSection
field - The field number
point - The point

Output Parameter

indices -The constrained dofs sorted in ascending order

Notes

The indices array, which is provided by the caller, must have capacity to hold the number of constrained dofs, e.g., as returned by PetscSectionGetConstraintDof().

Fortran Note

In Fortran, you call PetscSectionGetFieldConstraintIndicesF90() and PetscSectionRestoreFieldConstraintIndicesF90()
