Detailed Description

template<int dim, int spacedim = dim>
class FE_Enriched< dim, spacedim >::InternalData

A class to hold internal data needed for evaluation of this FE at quadrature points.

Constructor & Destructor Documentation

template<int dim, int spacedim>

FE_Enriched< dim, spacedim >::InternalData::InternalData

(

std::unique_ptr< typename FESystem< dim, spacedim >::InternalData >

fesystem_data

)

Constructor. Is used inside setup_data to wrap FESystem's internal data object. The former is called from get_data, get_subface_data and get_face_data which FE_Enriched has to implement.

Since FESystem::get_data(), FESystem::get_face_data() and FESystem::get_subface_data() just create an object and return a pointer to it (i.e. they don't retain ownership), we store the cast result in a std::unique_ptr to indicate that InternalData owns the object.

Member Function Documentation

template<int dim, int spacedim>

FiniteElement< dim, spacedim >::InternalDataBase & FE_Enriched< dim, spacedim >::InternalData::get_fe_data

(

const unsigned int

base_no

)

const

Give read-access to the pointer to a InternalData of the base_noth base element of FESystem's data.

Definition at line 1035 of file fe_enriched.cc.

template<int dim, int spacedim>

internal::FEValuesImplementation::FiniteElementRelatedData< dim, spacedim > & FE_Enriched< dim, spacedim >::InternalData::get_fe_output_object

(

const unsigned int

base_no

)

const

Give read-access to the pointer to an object into which the base_noth base element will write its output when calling FiniteElement::fill_fe_values() and similar functions.

Member Data Documentation

template<int dim, int spacedim = dim>

std::unique_ptr<typename FESystem<dim, spacedim>::InternalData> FE_Enriched< dim, spacedim >::InternalData::fesystem_data

Aggregate FESystem's internal data. It is used every time we call FESystem's fill_fe_values() and alike.

Definition at line 532 of file fe_enriched.h.

template<int dim, int spacedim = dim>

std::vector<std::vector<EnrichmentValues> > FE_Enriched< dim, spacedim >::InternalData::enrichment

mutable

For each FE used in enrichment (base number i) and each enrichment function (base multiplicity j), enrichment_values[i][j] will be used to store possibly requested values, gradients and hessians of enrichment function j.

The variable is made mutable as InternalData's provided to fill_fe_values and alike are const.

Note

We do not want to store this information in the finite element object itself, because this would mean that (i) only one FEValues object could use a finite element object at a time, and (ii) that these objects could not be used in a multithreaded context.
