Parameters

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

Returns

Integration result.

virtual void bem::rwg::ObsIntegratorBase::set_compute_terms ( bool  compute_g_term, bool  compute_rs_g_terms, bool  compute_grad_g_terms, bool  compute_rot_grad_g_terms  )

inlinevirtual

Sets flags defining which terms to compute during integration, which are propagated into the source triangle integration.

Parameters

[in]	compute_g_term	- If true, computes \[ \int_{\mathrm{obs\_tri}} d\mathcal{S}\, \int_{\mathrm{src\_tri}} d\mathcal{S}'\,G(k, \vec{r}, \vec{r}\,') \] for the scalar kernel \( G(k, \vec{r}, \vec{r}\,') \).
[in]	compute_rs_g_terms	- If true, computes terms related to \[ \int_{\mathrm{obs\_tri}} d\mathcal{S}\,\vec{r}\cdot \int_{\mathrm{src\_tri}} d\mathcal{S}'\,\vec{r}\,'\,G(k, \vec{r}, \vec{r}\,') \] for the scalar kernel \( G(k, \vec{r}, \vec{r}\,') \).
[in]	compute_grad_g_terms	- If true, computes terms related to \[ \int_{\mathrm{obs\_tri}} d\mathcal{S}\,\vec{r}\cdot \int_{\mathrm{src\_tri}} d\mathcal{S}'\,\nabla G(k, \vec{r}, \vec{r}\,')\times\vec{r}\,' \] for the scalar kernel \( G(k, \vec{r}, \vec{r}\,') \).
[in]	compute_rot_grad_g_terms	- If true, computes terms related to \[ \int_{\mathrm{obs\_tri}} d\mathcal{S}\,\hat{n}\times\vec{r}\cdot \int_{\mathrm{src\_tri}} d\mathcal{S}'\,\nabla G(k, \vec{r}, \vec{r}\,')\times\vec{r}\,' \] for the scalar kernel \( G(k, \vec{r}, \vec{r}\,') \).
