◆ VectorDoubleLayerProj()

template<typename SrcIntegratorType = SrcStrategic<>>

bem::rwg::VectorDoubleLayerProj< SrcIntegratorType >::VectorDoubleLayerProj ( const SrcIntegratorType src_integrator = SrcStrategic<>() )

◆ compute()

template<typename SrcIntegratorType >

EigMatXN< Complex, 3 > bem::rwg::VectorDoubleLayerProj< SrcIntegratorType >::compute	(	const Complex	k,
		ConstEigRef< EigMatNX< Float, 3 > >	obs_points,
		const Triangle< 3 > &	src_tri
	)

overridevirtual

Computes the vector double-layer projector.

Parameters

[in]	k	- Complex wavenumber.
[in]	obs_points	- Observation coordinates on which to project the generated field.
[in]	src_tri	- Source triangle.

Returns: Projected field components at each observation point, for each source degree of freedom.

Computes

\[ \int_{\mathrm{src\_tri}} d\mathcal{S}'\,\nabla G(k, \vec{r}, \vec{r}\,')\times\vec{f_n}(\vec{r}\,') \]

for each source triangle edge \( n \), where \( G(k, \vec{r}, \vec{r}\,') \) is a scalar kernel, and \( \vec{f_n}(\vec{r}) \) is the RWG function associated with edge \( n \). Rows of the output matrix are ordered by field components and then by observation points, and columns correspond to source edges. I.e., each column of the output looks like \( (F_{x1}, F_{y1}, F_{z1}), (F_{x2}, F_{y2}, F_{z2}), \ldots \), where \( (F_{xi}, F_{yi}, F_{zi}) \) are the components of the projected field \( \vec{F} \) defined at the observation point \( (x_i, y_i, z_i) \).

Implements bem::rwg::ProjectorBase< 3 >.
