Detailed Description

Linear form in 2D for coping the Dirichlet boundary for Identity bilinearform.

This linear form computes for elements with edges lying on the boundary

where

is the tangential vector,

the outer normal vector, and

the tangential component of the Neumann boundary.

Currently only on quadrilaterals.

Constructor

Parameters

dc	Local coefficients, which fullfill bc

Member Function Documentation

info()

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

protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::LinearForm< Real >.

operator()() [1/2]

void hp2Dedge::DirichletIdentity::operator()	(	const concepts::Element< Real > &	elm,
		concepts::ElementMatrix< Real > &	em
	)		const

Computes the element load vector. There are the loops over all quadrature points and the loops over all shape functions.

Parameters

elm	The element for which the load vector should be computed.
em	The load vector

operator()() [2/2]

virtual void concepts::LinearForm< Real , typename Realtype<Real >::type >::operator() ( const Element< typename Realtype<Real >::type > &  elm, ElementMatrix< Real > &  em  ) const

pure virtualinherited

Computes the element contribution to the function.

Parameters

elm	Element on which the computations should be performed
em	The local matrix
