Detailed Description

Static class to construct an element hp1D::LegendreElement out of an hp2Dedge::Quad.

The basis functions over the edge might be discontinuous. In derived classes the actual action can be specified, like taken the mean or the jump between the right and left side w.r.t. to the direction of the edge.

edge()

template<class F >

std::pair< hp1D::LegendreElement< F > *, concepts::Edge2d * > hp2Dedge::QuadEdgeBase::edge	(	const Quad< F > &	elm,
		const ushort	k,
		bool	emptyElm = true,
		hp1D::LegendreElement< F > *	edge = 0
	)

Returns the element and the geometrical cell as pair belonging to the k th edge in the quadrilateral element elm. The polynomial degree and the T matrix are set properly.

The geometrical cell is included in the element as reference, so it has to be deleted after deletion of the element.

If edge is given than degrees of freedom are added by adapting the T-matrix. This is the case when taking trace from both sides of an edge (e.g., mean or jump). In that case the cell is not returned in the pair, i.e., the returned pointer to the cell (Edge2d) is 0.

Parameters

emptyElm	Incorporate also empty elements (no dof).
edge	Element to which dof are added (adaptation of T-matrix)

info()

virtual std::ostream & hp2Dedge::QuadEdgeBase::info ( std::ostream &  os ) const

protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::OutputOperator.

Reimplemented in hp2Dedge::QuadEdgeFirst, hp2Dedge::QuadEdgeMean, and hp2Dedge::QuadEdgeJump.

weight_()

virtual Real hp2Dedge::QuadEdgeBase::weight_ ( bool  first, Z2  dir  ) const

protectedpure virtual

Returns the weight of the contribution of this cell to the edge

Parameters

first	flag if this is first contribution for this edge
dir	direction of the normal vector looking from the cell dir = 0 : inwards pointing dir = 1 : outwards pointing

Note, that in neighbouring cells the orientation of the edge is opposite.
