Detailed Description

template<int dim, int spacedim = dim>
class hp::MappingCollection< dim, spacedim >

This class implements a collection of mapping objects in the same way as the hp::FECollection implements a collection of finite element classes.

It implements the concepts stated in the hp Collections module described in the doxygen documentation.

Although it is recommended to supply an appropriate mapping for each finite element kind used in a hp-computation, the MappingCollection class implements a conversion constructor from a single mapping. Therefore it is possible to offer only a single mapping to the hp::FEValues class instead of a hp::MappingCollection. This is for the convenience of the user, as many simple geometries do not require different mappings along the boundary to achieve optimal convergence rates. Hence providing a single mapping object will usually suffice. See the hp::FEValues class for the rules which mapping will be selected for a given cell.

Constructor & Destructor Documentation

MappingCollection() [1/3]

template<int dim, int spacedim = dim>

hp::MappingCollection< dim, spacedim >::MappingCollection ( )

default

Default constructor. Leads to an empty collection that can later be filled using push_back().

MappingCollection() [2/3]

template<int dim, int spacedim>

hp::MappingCollection< dim, spacedim >::MappingCollection ( const Mapping< dim, spacedim > &  mapping )

explicit

Conversion constructor. This constructor creates a MappingCollection from a single mapping. More mappings can be added with push_back(), if desired, though it would probably be clearer to add all mappings the same way.

MappingCollection() [3/3]

template<int dim, int spacedim>

hp::MappingCollection< dim, spacedim >::MappingCollection

(

const MappingCollection< dim, spacedim > &

mapping_collection

)

Copy constructor.

Member Function Documentation

push_back()

template<int dim, int spacedim>

void hp::MappingCollection< dim, spacedim >::push_back

(

const Mapping< dim, spacedim > &

new_mapping

)

Adds a new mapping to the MappingCollection. Generally, you will want to use the same order for mappings as for the elements of the hp::FECollection object you use. However, the same considerations as discussed with the hp::QCollection::push_back() function also apply in the current context.

This class creates a copy of the given mapping object, i.e., you can do things like push_back(MappingQ<dim>(3));. The internal copy is later destroyed by this object upon destruction of the entire collection.

operator[]()

template<int dim, int spacedim>

const Mapping< dim, spacedim > & hp::MappingCollection< dim, spacedim >::operator[] ( const unsigned int  index ) const

inline

Return the mapping object which was specified by the user for the active_fe_index which is provided as a parameter to this method.

Precondition

index must be between zero and the number of elements of the collection.

Definition at line 162 of file mapping_collection.h.

size()

template<int dim, int spacedim>

unsigned int hp::MappingCollection< dim, spacedim >::size ( ) const

inline

Return the number of mapping objects stored in this container.

Definition at line 152 of file mapping_collection.h.

memory_consumption()

template<int dim, int spacedim>

std::size_t hp::MappingCollection< dim, spacedim >::memory_consumption

(

)

const

Determine an estimate for the memory consumption (in bytes) of this object.

Definition at line 58 of file mapping_collection.cc.

Member Data Documentation

mappings

template<int dim, int spacedim = dim>

std::vector<std::shared_ptr<const Mapping<dim,spacedim> > > hp::MappingCollection< dim, spacedim >::mappings
