An explicit kernel-split panel-based Nyström scheme for integral equations on axially symmetric surfaces

Helsing, Johan LU and Karlsson, Anders LU (2014) In Journal of Computational Physics 272. p.686-703
Abstract
A high-order accurate, explicit kernel-split, panel-based, Fourier–Nyström discretization scheme is developed for integral equations associated with the Helmholtz equation in axially symmetric domains. Extensive incorporation of analytic information about singular integral kernels and on-the-fly computation of nearly singular quadrature rules allow for very high achievable accuracy, also in the evaluation of fields close to the boundary of the computational domain.
