Detailed Description

template<int dim, int spacedim = dim>
struct hp::FECollection< dim, spacedim >::DefaultHierarchy

Whenever p adaptivity is considered in an hp finite element program, a hierarchy of finite elements needs to be established to determine succeeding finite elements for refinement and preceding ones for coarsening.

In this struct, we supply a hierarchy that is imposed on all FECollection objects by default.

Member Function Documentation

next_index()

template<int dim, int spacedim = dim>

static unsigned int hp::FECollection< dim, spacedim >::DefaultHierarchy::next_index ( const typename hp::FECollection< dim, spacedim > &  fe_collection, const unsigned int  fe_index  )

inlinestatic

Return the index succeeding fe_index in the fe_collection.

Once the last element of the fe_collection is reached, there is no element on a higher level in the hierarchy and thus we return the last value.

Definition at line 75 of file fe_collection.h.

previous_index()

template<int dim, int spacedim = dim>

static unsigned int hp::FECollection< dim, spacedim >::DefaultHierarchy::previous_index ( const typename hp::FECollection< dim, spacedim > &  fe_collection, const unsigned int  fe_index  )

inlinestatic

Return the index preceding fe_index in the fe_collection.

Once the first element of the fe_collection is reached, there is no element on a lower level in the hierarchy and thus we return the first value.
