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

Note#

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#

Use PetscSectionGetFieldConstraintIndicesF90() and PetscSectionRestoreFieldConstraintIndicesF90()
