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 Many brpointwise values are not defined on the element boundaries), or if the implementation of PetscDualSpace does not Many brsupport extracting subspaces, then NULL is returned. Many br

This does not increment the reference count on the returned dual space, and the user should not destroy it. Many br

Not collective Many br

Input Parameters

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

Output Parameters

bdsp - the subspace: must be destroyed by the user Many br
