Detailed Description

template<class TestField, class TrialField, size_t order>
class NiHu::helmholtz_2d_DLP_galerkin_face_general< TestField, TrialField, order >

Face match double integral of the DLP kernel.

The integration domain is split up into two triangles, both are singular. A new coordinate transform is introduced where the singularity is attributed to a single variable. In the new system the integrand becomes regular, and is integrated using Gaussian quadrature. https://doi.org/10.1016/S0045-7825(03)00286-X
