◆ clone() [1/2]

template<class F = Real>

virtual LaplaceMatrix<F>* hp2D::LaplaceMatrix< 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 , typename Realtype<Real >::type >::clone ( ) const

pure virtualinherited

Virtual constructor.

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

◆ computeadjJ_adjJT_rank1_()

void hp2D::BilinearFormHelper_1_1< Real , Real >::computeadjJ_adjJT_rank1_	(	concepts::Array< concepts::Mapping< Real, 2 > > &	intermediateMatrix,
		const int	i,
		const int	j
	)		const

privateinherited

Computes the either adj(J)*adj(J)^T or in the case of partial derivatives (i > NONE, j > NONE) the rank-1 product of j-th column of adj(J) with i-th row of adj(J)^T.

◆ computeIntermediate_()

void hp2D::BilinearFormHelper_1_1< Real , Real >::computeIntermediate_	(	const BaseQuad< Real > &	elm,
		const int	i = `-1`,
		const int	j = `-1`
	)		const

protectedinherited

Compute the intermediate data for element matrix computation.

Parameters

i	if i=0 or 1, then take only i-th column of Jacobian matrix (for test function)
j	if j=0 or 1, then take only j-th column of Jacobian matrix (for trial function)

The Jacobian matrices have to been taken both full (i,j = -1) or both partial (i,j = 0 or 1).

Matrix formulas and complex valued scalar formulas are only implemented for full Jacobians.

◆ computeJacobianMatrix_()

void hp2D::BilinearFormHelper_1_1< Real , Real >::computeJacobianMatrix_	(	const BaseQuad< Real > &	elm,
		concepts::Array< concepts::Mapping< Real, 2 > > &	J,
		concepts::Array< Real > &	detJ_inv
	)		const

privateinherited

Compute the Jacobian matrix and the inverse of its determinant on each quadrature point.

◆ data() [1/2]

concepts::RCP<concepts::SharedJacobianAdj<2> > hp2D::BilinearFormHelper_1_1< Real , Real >::data

inherited

Gets the pointer to the shared data.

◆ data() [2/2]

void hp2D::BilinearFormHelper_1_1< Real , Real >::data ( const concepts::RCP< concepts::SharedJacobianAdj< 2 > > d )

inherited

Set the pointer to the shared data.

◆ info()

template<class F = Real>

virtual std::ostream& hp2D::LaplaceMatrix< F >::info ( std::ostream & os ) const

protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::BilinearForm< Real >.

		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 , typename Realtype<Real >::type >::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`
