Detailed Description

template<typename TriangleQuadratureType = GaussTriangleQuadrature<2>, typename LineQuadratureType = GaussLineQuadrature<1>>
class bem::rwg::SrcStrategic< TriangleQuadratureType, LineQuadratureType >

Class integration over the source triangle for RWG-based BEM operators. The method of integration is chosen automatically and strategically based on mesh parameters, materials, and frequency.

Template Parameters

TriangleQuadratureType	- Type of the triangle quadrature object, which must derive from `TriangleQuadratureBase<2>`.
LineQuadratureType	- Type of the line quadrature object, which must derive from `LineQuadratureBase<1>`.

inlinevirtualinherited

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 \( G(k, \vec{r}, \vec{r}\,') \).

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

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 \(\vec{r}\,' = [x', y']^T\).
