Detailed Description

template<class RLV, class PP>
class Dune::Functions::SubspaceLocalView< RLV, PP >

The restriction of a finite element basis to a single element.

Member Typedef Documentation

◆ Element

template<class RLV , class PP >

using Dune::Functions::SubspaceLocalView< RLV, PP >::Element = typename GridView::template Codim<0>::Entity

Type of the grid element we are bound to.

◆ GlobalBasis

template<class RLV , class PP >

using Dune::Functions::SubspaceLocalView< RLV, PP >::GlobalBasis = SubspaceBasis<typename RootLocalView::GlobalBasis, PrefixPath>

The global FE basis that this is a view on.

◆ GridView

template<class RLV , class PP >

using Dune::Functions::SubspaceLocalView< RLV, PP >::GridView = typename GlobalBasis::GridView

The grid view the global FE basis lives on.

◆ MultiIndex

template<class RLV , class PP >

using Dune::Functions::SubspaceLocalView< RLV, PP >::MultiIndex = typename RootLocalView::MultiIndex

Type used for global numbering of the basis vectors.

◆ RootLocalView

template<class RLV , class PP >

using Dune::Functions::SubspaceLocalView< RLV, PP >::RootLocalView = RLV

◆ RootTree

template<class RLV , class PP >

using Dune::Functions::SubspaceLocalView< RLV, PP >::RootTree = typename RootLocalView::Tree

Tree of local finite elements / local shape function sets.

◆ size_type

template<class RLV , class PP >

using Dune::Functions::SubspaceLocalView< RLV, PP >::size_type = std::size_t

The type used for sizes.

◆ Tree

template<class RLV , class PP >

using Dune::Functions::SubspaceLocalView< RLV, PP >::Tree = typename TypeTree::ChildForTreePath<RootTree, PrefixPath>

Tree of local finite elements / local shape function sets.

Constructor & Destructor Documentation

◆ SubspaceLocalView()

template<class RLV , class PP >

Dune::Functions::SubspaceLocalView< RLV, PP >::SubspaceLocalView	(	const GlobalBasis &	globalBasis,
		const PrefixPath &
	)

inline

Construct local view for a given global finite element basis.

Member Function Documentation

◆ bind()

template<class RLV , class PP >

void Dune::Functions::SubspaceLocalView< RLV, PP >::bind ( const Element & e )

inline

Bind the view to a grid element.

Having to bind the view to an element before being able to actually access any of its data members offers to centralize some expensive setup code in the 'bind' method, which can save a lot of run-time.

◆ bound()

template<class RLV , class PP >

bool Dune::Functions::SubspaceLocalView< RLV, PP >::bound ( ) const

inline

Return if the view is bound to a grid element.

◆ element()

template<class RLV , class PP >

const Element & Dune::Functions::SubspaceLocalView< RLV, PP >::element ( ) const

inline

Return the grid element that the view is bound to.

Exceptions

Dune::Exception if the view is not bound to anything

◆ globalBasis()

template<class RLV , class PP >

const GlobalBasis & Dune::Functions::SubspaceLocalView< RLV, PP >::globalBasis ( ) const

inline

Return the global basis that we are a view on.

◆ index()

template<class RLV , class PP >

MultiIndex Dune::Functions::SubspaceLocalView< RLV, PP >::index ( size_type i ) const

inline

Maps from subtree index set [0..size-1] to a globally unique multi index in global basis.

◆ maxSize()

template<class RLV , class PP >

size_type Dune::Functions::SubspaceLocalView< RLV, PP >::maxSize ( ) const

inline

Maximum local size for any element on the GridView.

This is the maximal size needed for local matrices and local vectors, i.e., the result is

◆ rootLocalView()

template<class RLV , class PP >

const RootLocalView & Dune::Functions::SubspaceLocalView< RLV, PP >::rootLocalView ( ) const

inline

◆ size()

template<class RLV , class PP >

size_type Dune::Functions::SubspaceLocalView< RLV, PP >::size ( ) const

inline

Total number of degrees of freedom on this element.

◆ tree()

template<class RLV , class PP >

const Tree & Dune::Functions::SubspaceLocalView< RLV, PP >::tree ( ) const

inline

Return the local ansatz tree associated to the bound entity.

Returns: Tree // This is tree

◆ unbind()

template<class RLV , class PP >

void Dune::Functions::SubspaceLocalView< RLV, PP >::unbind ( )

inline

Unbind from the current element.

Calling this method should only be a hint that the view can be unbound.
