Abstract :
A new quadrature scheme for evaluating near singular integrals on curvilinear triangular domains has been presented. Results for the static kernel has demonstrated the significant benefits of the scheme. Progress with respect to employing the scheme within a comprehensive, time-harmonic MoM code with curvilinear elements and higher-order basis functions, will be reported at the symposium.
