Detailed Description

Volume integral for the identity in DG FEM in 2D. This bilinear form integrates

$\int_{K} \phi_i \cdot \phi_j \, dx.$

Member Function Documentation

◆ clone()

virtual IdentityBf * linDG2D::IdentityBf::clone ( ) const

inlinevirtual

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

Implements concepts::BilinearForm< Real >.

Definition at line 31 of file bilinearForm.hh.

◆ info()

virtual std::ostream & concepts::BilinearForm< Real , typename Realtype<Real >::type >::info ( std::ostream & os ) const

protectedvirtualinherited

Returns information in an output stream.

Reimplemented from concepts::OutputOperator.

Reimplemented in hp2D::DivDiv< Weight >, hp2D::RotRot, hp2Dedge::Rotuv, hp2Dedge::EdgeIdentity, hp3D::DivDiv< Weight >, hp3D::Hook, and hp3D::RotRot.

◆ operator()() [1/2]

virtual void concepts::BilinearForm< Real , typename Realtype<Real >::type >::operator()	(	const Element< typename Realtype<Real >::type > &	elmX,
		const Element< typename Realtype<Real >::type > &	elmY,
		ElementMatrix< Real > &	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()() [2/2]

virtual void concepts::BilinearForm< Real , typename Realtype<Real >::type >::operator()	(	const Element< typename Realtype<Real >::type > &	elmX,
		const Element< typename Realtype<Real >::type > &	elmY,
		ElementMatrix< Real > &	em,
		const ElementPair< typename Realtype<Real >::type > &	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`
