Detailed Description

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

Class for Gaussian quadrature over a triangle.

Template Parameters

dim	- Dimension of the triangle (2 or 3).

Definition at line 43 of file gauss.hpp.

Constructor & Destructor Documentation

◆ GaussTriangleQuadrature()

template<uint8_t dim>

bem::GaussTriangleQuadrature< dim >::GaussTriangleQuadrature ( const uint8_t order = TRI_DEFAULT_ORDER )

inline

Constructs a GaussTriangleQuadrature 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 TRI_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::GaussTriangleQuadrature< dim >::set_order ( const uint8_t order )

overridevirtual

Sets the quadrature order.

Parameters

[in] order - Quadrature order.

Reimplemented from bem::TriangleQuadratureBase< dim >.

◆ compute_points_weights()

template<uint8_t dim>

void bem::GaussTriangleQuadrature< dim >::compute_points_weights	(	const Triangle< dim > &	tri,
		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]	tri	- Triangle for quadrature evaluation.
[in]	eval	- Function or class with `operator()` that evaluates the integrand (optional, unused).

Implements bem::TriangleQuadratureBase< dim >.
