Detailed Description

template<class F = Real>
class hp1D::IdentityParallel< F >

A function class to calculate element matrices for the mass matrix for elements that are shifted.

There are two independent coordinate shifts for the trial and test function. In contrast to hp1D::Identity the elements do not need to have overlapping support but their shifted start and end points have to be identical. Note that the orientation of the two elements may also be of reverse direction. If negShift is set to true it is checked as well whether a coordinate shift with opposite sign matches the criterion.

Member Function Documentation

clone() [1/2]

template<class F = Real>

virtual IdentityParallel<F>* hp1D::IdentityParallel< F >::clone ( ) const

virtual

Virtual constructor.

Returns a pointer to a copy of itself. The caller is responsible to destroy this copy.

Implements concepts::Cloneable.

clone() [2/2]

virtual BilinearForm* concepts::BilinearForm< Real , Real >::clone ( ) const

pure virtualinherited

Virtual constructor.

Returns a pointer to a copy of itself. The caller is responsible to destroy this copy.

info()

template<class F = Real>

virtual std::ostream& hp1D::IdentityParallel< F >::info ( std::ostream &  os ) const

protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::BilinearForm< Real, Real >.

operator()() [1/3]

template<class F = Real>

void hp1D::IdentityParallel< F >::operator()	(	const concepts::Element< Real > &	elmX,
		const concepts::Element< Real > &	elmY,
		concepts::ElementMatrix< F > &	em
	)		const

operator()() [2/3]

virtual void concepts::BilinearForm< Real , Real >::operator() ( const Element< G > &  elmX, const Element< G > &  elmY, ElementMatrix< F > &  em  ) const

pure virtualinherited

Evaluates the bilinear form for all shape functions on elmX and elmY and stores the result in the matrix em.

Postcondition

The returned matrix em has the correct size.

Parameters

elmX	Left element (test functions)
elmY	Right element (trial functions)
em	Return element matrix

operator()() [3/3]

virtual void concepts::BilinearForm< Real , Real >::operator() ( const Element< G > &  elmX, const Element< G > &  elmY, ElementMatrix< F > &  em, const ElementPair< G > &  ep  ) const

inlinevirtualinherited

Evaluates the bilinear form for all shape functions on elmX and elmY and stores the result in the matrix em.

If this method is not reimplemented in a derived class, the default behaviour is to call the application operator without ep.

Postcondition

The returned matrix em has the correct size.

Parameters

elmX	Left element
elmY	Right element
em	Return element matrix
ep	Element pair holding more information on the pair elmX and elmY
