Edge match double integral of the HSP kernel.
The integration domain is split up into two triangles, one of them is singular. The singularity is weakened by a coordinate transform. The remaining \(O(1/r)\) singularity is subtracted and integrated analytically in a HFP sense. The remaining regular integral is evaluated numerically. https://doi.org/10.1016/S0045-7825(03)00286-X
