PetscDualSpaceGetHeightSubspace

Get the subset of the dual space basis that is supported on a mesh point of a given height.

Synopsis

#include "petscfe.h" 
PetscErrorCode PetscDualSpaceGetHeightSubspace(PetscDualSpace sp, PetscInt height, PetscDualSpace *bdsp)
If the dual space is not defined on mesh points of the given height (e.g. if the space is discontinuous and pointwise values are not defined on the element boundaries), or if the implementation of PetscDualSpace does not support extracting subspaces, then NULL is returned.

Input Parameters

sp - the PetscDualSpace object
height - the height of the mesh point for which the subspace is desired

Output Parameters

bdsp - the subspace: must be destroyed by the user
