Detailed Description

template<class GV, class SDPB, class SD>
class Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >

A pre-basis restricted to a sub-domain.

This pre-basis wraps another pre-basis and restricts it to a sub-domain. The wrapped pre-basis is assumed to be defined on a sub-domain of the full grid view. Then the RestrictedPreBasis defines a pre-basis on the full grid view implemented in terms of the pre-basis on the sub-domain. Most of the methods are forwarded to the sub-domain pre-basis with two exceptions: When binding a RestrictedPreBasis::Node, this only calls subDomainNode.bind(element) if the element is contained in the sub-domain, otherwise the sizes of the node and all its descendents is set to zero. Furthermore it only calls subDomainPreBasis.indices(node,it) if node.size() is not zero.

Template Parameters

GV	Type of the (full) grid view this pre-basis is defined on.
SDPB	Type of a pre-basis defined on sub-set of the full grid view
SD	Type of the sub-domain

template<class GV, class SDPB, class SD>

using Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >::GridView = GV

The grid view that the FE basis is defined on.

◆ size_type

template<class GV, class SDPB, class SD>

using Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >::size_type = std::size_t

Type used for indices and size information.

◆ SubDomain

template<class GV, class SDPB, class SD>

using Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >::SubDomain = SD

◆ SubDomainGridView

template<class GV, class SDPB, class SD>

using Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >::SubDomainGridView = typename SubDomainPreBasis::GridView

◆ SubDomainPreBasis

Constructor & Destructor Documentation

◆ RestrictedPreBasis()

template<class GV, class SDPB, class SD>

Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >::RestrictedPreBasis	(	const GridView &	gridView,
		SubDomainPreBasis &&	subDomainPreBasis,
		const SubDomain &	subDomain )

inline

Constructor for given sub-domain pre-basis.

The grid view and sub-domain pre-basis will be stored as copy while a pointer to the sub-domain object is stored.

Member Function Documentation

◆ containerDescriptor()

template<class GV, class SDPB, class SD>

auto Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >::containerDescriptor ( ) const

inline

Return the container descriptor of the pre-basis.

◆ dimension()

template<class GV, class SDPB, class SD>

size_type Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >::dimension ( ) const

inline

Get the total dimension of the space spanned by this basis.

◆ gridView()

template<class GV, class SDPB, class SD>

const GridView & Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >::gridView ( ) const

inline

Obtain the grid view that the basis is defined on.

◆ indices()

template<class GV, class SDPB, class SD>

template<typename It>

It Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >::indices	(	const Node &	node,
		It	it ) const

inline

◆ initializeIndices()

template<class GV, class SDPB, class SD>

void Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >::initializeIndices ( )

inline

Initialize the global indices.

◆ makeNode()

template<class GV, class SDPB, class SD>

Node Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >::makeNode ( ) const

inline

Create tree node.

◆ maxNodeSize()

template<class GV, class SDPB, class SD>

size_type Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >::maxNodeSize ( ) const

inline

Get the maximal number of DOFs associated to node for any element.

◆ size() [1/2]

template<class GV, class SDPB, class SD>

size_type Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >::size ( ) const

inline

Same as size(prefix) with empty prefix.

◆ size() [2/2]

template<class GV, class SDPB, class SD>

template<class SizePrefix>

size_type Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >::size ( const SizePrefix & prefix ) const

inline

Return number of possible values for next position in multi index.

◆ subDomainPreBasis() [1/2]

template<class GV, class SDPB, class SD>

SubDomainPreBasis & Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >::subDomainPreBasis ( )

inline

◆ subDomainPreBasis() [2/2]

template<class GV, class SDPB, class SD>

const SubDomainPreBasis & Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >::subDomainPreBasis ( ) const

inline

◆ update()

template<class GV, class SDPB, class SD>

void Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >::update ( const GridView & gv )

inline

Update the stored grid view, to be called.

This will also call subDomainPreBasis.update(subDomainPtr->gridView()) with the stored sub-domain pointer to update the sub-domain pre-basis. Hence it requires the subDomain object passed to the present pre-basis has been correctly updated externally, before calling this method.
