PCBDDCGetDirichletBoundariesLocal

Get parallel IS for Dirichlet boundaries (in local ordering)

Synopsis

#include "petscpc.h" 
PetscErrorCode PCBDDCGetDirichletBoundariesLocal(PC pc, IS *DirichletBoundaries)

Collective

Input Parameter

• pc - the preconditioning context

Output Parameter

• DirichletBoundaries - index set defining the subdomain part of Dirichlet boundaries

Note

The IS returned could be the same passed in earlier by the user (if provided with PCBDDCSetDirichletBoundariesLocal()) or a global-to-local map of the global IS (if provided with PCBDDCSetDirichletBoundaries()). In the latter case, the IS will be available only after PCSetUp().
