Parameters

elm1	First element
elm2	Second element
faceIdx1	Index of face in first element
faceIdx2	Index of face in second element

FvdgElementPair() [2/2]

linDG3D::FvdgElementPair::FvdgElementPair	(	const FvdgElement &	elm,

Member Function Documentation

area()

Real linDG3D::FvdgElementPair::area ( ) const

inline

Returns the area of the common face.

Definition at line 49 of file elementPair.hh.

diam()

Real linDG3D::FvdgElementPair::diam ( ) const

inline

Returns the diameter of the common face.

Definition at line 51 of file elementPair.hh.

edgeIndex()

uint linDG3D::FvdgElementPair::edgeIndex	(	uint	elem,
		uint	edge
	)		const

Returns an edge index. The edge index is according to the element's internal numbering so that it can be used to query information.

Parameters

elem	Index of the element in consideration (either 0 or 1)
edge	Index of the edge in the common face

Returns

Index of edge edge in element elem of the pair

elm1()

virtual const FvdgElement & linDG3D::FvdgElementPair::elm1 ( ) const

inlinevirtual

Returns reference to the first element.

Implements concepts::ElementPair< Real >.

Definition at line 45 of file elementPair.hh.

elm2()

virtual const FvdgElement & linDG3D::FvdgElementPair::elm2 ( ) const

inlinevirtual

Returns reference to the second element.

Implements concepts::ElementPair< Real >.

Definition at line 46 of file elementPair.hh.

faceIdx1()

uint linDG3D::FvdgElementPair::faceIdx1 ( ) const

inline

Returns the index of the face in element 1.

Definition at line 87 of file elementPair.hh.

faceIdx2()

uint linDG3D::FvdgElementPair::faceIdx2 ( ) const

inline

Returns the index of the face in element 2.

Definition at line 89 of file elementPair.hh.

normal()

concepts::Real3d linDG3D::FvdgElementPair::normal ( ) const

inline

Returns the normal vector of the common face.

Definition at line 53 of file elementPair.hh.

numPairs()

uint linDG3D::FvdgElementPair::numPairs ( ) const

inline

Returns the number of common edges.

Definition at line 55 of file elementPair.hh.

quadrature() [1/2]

void linDG3D::FvdgElementPair::quadrature	(	std::vector< Real > &	weights,
