Detailed Description

template<uint8_t dim>
class bem::GaussLineQuadrature< dim >

Class for Gaussian quadrature over a line segment.

Template Parameters

dim	- Dimension of the line segment (1, 2, or 3).

Definition at line 44 of file gauss.hpp.

Constructor & Destructor Documentation

◆ GaussLineQuadrature()

template<uint8_t dim>

bem::GaussLineQuadrature< dim >::GaussLineQuadrature ( const uint8_t order = LINE_DEFAULT_ORDER )

inline

Constructs a GaussLineQuadrature object with a specified quadrature order.

Parameters

[in] order - Quadrature order (optional).

Important: this constructor loads tabulated quadrature data from a json file, and stores the tabulated quadrature data for all possible orders up to LINE_MAX_ORDER. Therefore, it is strongly recommended that objects of this class should be reused within loops, rather than creating a new object at each iteration of a long loop.

◆ set_order()

template<uint8_t dim>

void bem::GaussLineQuadrature< dim >::set_order ( const uint8_t order )

overridevirtual

Sets the quadrature order.

Parameters

◆ compute_points_weights()

template<uint8_t dim>

void bem::GaussLineQuadrature< dim >::compute_points_weights	(	ConstEigRef< EigColVecN< Float, dim > >	p1,
		ConstEigRef< EigColVecN< Float, dim > >	p2,
		std::function< EigRowVec< Complex >(ConstEigRef< EigMatNX< Float, dim > >)>	eval = `{}`
	)

overridevirtual

Computes and stores the points on which to evaluate the integrand, and the corresponding weights.

Parameters

[in]	p1	- First point of the line segment.
[in]	p2	- Second point of the line segment.
[in]	eval	- Function or class with `operator()` that evaluates the integrand (optional, unused).
