The evaluation of the inverse distance singular integrand which occurs in the three-dimensional boundary element formulation of potential problems is treated using weighted Gaussian integration. Three methods are investigated. The first involves repeated use of a one-dimensional Gaussian formula in
The e cient numerical evaluation of integrals arising in the boundary element method is of considerable practical importance. The superiority of the use of sigmoidal and semi-sigmoidal transformations together with Gauss-Legendre quadrature in this context has already been well-demonstrated numerica
