Detailed Description

template<class GridPartImp, class IntegrationTraits>
class Dune::Fem::ElementIntegrationPointList< GridPartImp, 1, IntegrationTraits >

constructor

Parameters

[in]	gridPart	grid partition (a dummy here)
[in]	intersection	intersection
[in]	quadKey	quadrature key, i.e. desired order of the quadrature
[in]	side	either INSIDE or OUTSIDE; codim-0 entity for which the ElementQuadrature shall be created

Note

This code assumes that the codim-0 entity is either a simplex or a cube (otherwise elementGeometry() returns a wrong geometry).

Parameters

[in]	gridPart	grid partition (a dummy here)
[in]	intersection	intersection
[in]	quadKey	quadrature key, i.e. desired order of the quadrature

Member Function Documentation

elementGeometry()

GeometryType Dune::Fem::ElementPointListBase< GridPartImp, codim, IntegrationTraits >::elementGeometry ( ) const

inlineinherited

obtain GeometryType of the corresponding codim-0 the integration point list belongs to

An element integration point list can return the coordinates of integration points with resepct to the codim-0 reference element and the reference element corresponding to the subentity the quadrature actually lives on. This method returns the geometry of the codim-0 entity.

Note

Calling this method yields a virtual function call, so do not call this method unnecessarily.

Returns

GeometryType for this integration point list

id()

size_t Dune::Fem::ElementPointListBase< GridPartImp, codim, IntegrationTraits >::id ( ) const

inlineinherited

obtain the identifier of the integration point list

The identifier of an integration point list must be globally unique. Even integration point lists for different dimensions must have different identifiers.

Note

Quadratures are considered distinct if they differ in one of the following points: geometry type, order, dimension or implementation.

Returns

globally unique identifier of the integration point list

localPoint()

const LocalCoordinateType& Dune::Fem::ElementPointListBase< GridPartImp, codim, IntegrationTraits >::localPoint ( size_t  i ) const

inlineinherited

obtain local coordinates of i-th integration point

This method returns a reference to the local coordinates of the i-th integration point for 0 <= i < nop(). Here, local coordinates means coordinates with respect to the reference element of the subentity.

Parameters

[in]

i

number of the integration point, 0 <= i < nop()

Returns

reference to i-th integration point

nop()

size_t Dune::Fem::ElementPointListBase< GridPartImp, codim, IntegrationTraits >::nop ( ) const

inlineinherited

obtain the number of integration points

Returns

number of integration points within this list

order()

int Dune::Fem::ElementPointListBase< GridPartImp, codim, IntegrationTraits >::order ( ) const

inlineinherited

obtain order of the integration point list

The order of a quadrature is the maximal polynomial degree that is guaranteed to be integrated exactly by the quadrature.

In case of an integration point list, the definition of this value is left to the implementor.

Note

Calling this method yields a virtual function call, so do not call this method unnecessarily.

Returns

the order of the integration point list

point()

template<class GridPartImp , class IntegrationTraits >

const CoordinateType& Dune::Fem::ElementIntegrationPointList< GridPartImp, 1, IntegrationTraits >::point ( size_t  i ) const

inline

obtain coordinates of i-th integration point

This method returns a reference to the coordinates of the i-th integration point for 0 <= i < nop(). The integration point is given in local coordinates, i.e., coordinates with respect to the reference element.

Parameters

[in]

i

number of the integration point, 0 <= i < nop()

Returns

reference to i-th integration point

quadImp()

const IntegrationPointListType& Dune::Fem::ElementPointListBase< GridPartImp, codim, IntegrationTraits >::quadImp ( ) const

inlineprotectedinherited

obtain the actual implementation of the quadrature

Note

This method may only be used in derived classes.

Returns

a reference to the actual implementation of the quadrature
