Constructor & Destructor Documentation

template<typename BasisFunctionType , typename ResultType >

Bempp::AbstractBoundaryOperatorComposition< BasisFunctionType, ResultType >::AbstractBoundaryOperatorComposition	(	const BoundaryOperator< BasisFunctionType, ResultType > &	outer,
		const BoundaryOperator< BasisFunctionType, ResultType > &	inner,
		int	symmetry = `NO_SYMMETRY`
	)

Constructor.

Construct an operator representing the product $M \equiv L_1 L_2 : X \to Z$ of two boundary operators $L_1 : Y \to Z$ and $L_2 : X \to Y$ .

Parameters

[in]	outer	Operator .
[in]	inner	Operator .
[in]	symmetry	(Optional) Symmetry of the weak form of the composite operator. Can be any combination of the flags defined in the enumeration type Symmetry.

Note: Both operators must be initialized and the range space of the operator inner must be identical with the domain space of the operator outer, otherwise an exception is thrown.

Todo:: Add a parameter setting the symmetry of the composite operator.

shared_ptr< DiscreteBoundaryOperator< ResultType > > Bempp::AbstractBoundaryOperatorComposition< BasisFunctionType, ResultType >::assembleWeakFormImpl ( const Context< BasisFunctionType, ResultType > & context ) const

protectedvirtual

Assemble and return the operator's weak form.

This virtual function is invoked by assembleWeakForm() to do the actual work.

Implements Bempp::AbstractBoundaryOperator< BasisFunctionType_, ResultType_ >.

template<typename BasisFunctionType , typename ResultType >

bool Bempp::AbstractBoundaryOperatorComposition< BasisFunctionType, ResultType >::isLocal ( ) const

virtual

Return whether this operator is local.

Suppose that an operator $A$ acting on a function $f(x)$ produces another function $g(x)$ . We say that $A$ is local if the value of $g$ at any point $x$ depends only on the values of $f$ in an infinitesimal neighbourhood of $x$ .

Multiplicative and differential operators are local and discretization of their weak forms with finite elements leads to sparse matrices. Conversely, integral operators are in general non-local and discretization of their weak forms leads to dense matrices.
