Detailed Description

template<typename ObsIntegratorType = ObsStrategic<>>
class bem::rwg::RotGradScalarSingleLayerOp< ObsIntegratorType >

Class for computing the rotationally-tested gradient of the scalar single-layer potential operator.

Template Parameters

ObsIntegratorType - Type of the observation triangle integrator, must derive from ObsIntegratorBase.

Computes

\[ \int_{\mathrm{obs\_tri}} d\mathcal{S}\,\hat{n}\times\vec{f_m}(\vec{r})\cdot \nabla\int_{\mathrm{src\_tri}} d\mathcal{S}'\,G(k, \vec{r}, \vec{r}\,')\,h(\vec{r}\,') \]

for observation triangle edge \( m \), where \( G(k, \vec{r}, \vec{r}\,') \) is a scalar kernel, \( \vec{f_i}(\vec{r}) \) is the RWG function associated with edge \( i \), \( h(\vec{r}) \) is a pulse function that is a non-zero constant inside the associated triangle, and zero outside, and \( \hat{n} \) is the unit normal vector associated with obs_tri. Rows of the output matrix correspond to observation edges.
