LIST OF METHODS

CalcG is the method that accurately computes the surface integral $\int_{\Delta S}{G(\vec{r},\vec{r}^{\,\prime})dS^{\,\prime}}$ where $G(\vec{r},\vec{r}^{\,\prime})=\frac{e^{-i k R}}{4\pi R}$ is the Helmholtz kernel regardless of how close is the observation point $\vec{r}$ to the triangle $\Delta S$. Although this integral does not typically arise in BEM, the method is written for test purposes.
