◆ integrate()

virtual SrcResult bem::rwg::SrcIntegratorBase::integrate	(	const Complex	k,
		const Triangle< 2 > &	src_tri,
		ConstEigRef< EigMatNX< Float, 3 > >	r_obs
	)

pure virtual

Computes the integral over the source triangle.

Parameters

[in]	k	- Complex wavenumber.
[in]	src_tri	- Source triangle in 2D space.
[in]	r_obs	- Observation points in the local coordinate system of `src_tri`.

Returns: Integration result.

◆ set_compute_terms()

virtual void bem::rwg::SrcIntegratorBase::set_compute_terms	(	bool	compute_g_terms,
		bool	compute_grad_g_terms
	)

inlinevirtual

Sets flags defining which terms to compute during integration.

Parameters

[in]

compute_g_terms

- If true, computes

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

and

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

for the scalar kernel \( G(k, \vec{r}, \vec{r}\,') \).

[in]

compute_grad_g_terms

- If true, computes

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

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

and

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

for the scalar kernel \( G(k, \vec{r}, \vec{r}\,') \), and for local source triangle coordinates \(\vec{r}\,' = [x', y']^T\).

◆ zeros()

virtual SrcResult bem::rwg::SrcIntegratorBase::zeros	(	const Complex	k,
		const Triangle< 2 > &	src_tri,
		ConstEigRef< EigMatNX< Float, 3 > >	r_obs
	)

inlinevirtual

Returns a result of zeros of the appropriate size.

Parameters

[in]	k	- Complex wavenumber.
[in]	src_tri	- Source triangle in 2D space.
[in]	r_obs	- Observation points in the local coordinate system of `src_tri`.

Returns: Integration result.
