  • Abstract
    This paper presents the numerical solution of strongly near-singular integrals, involving the gradient of Helmholtz-type potentials, defined over curvilinear elements. The proposed numerical integration scheme is based on appropriate variable transformations able to exactly cancel the nearly singular kernel.
