Abstract :
In this paper we present new regular polyhedra quadrature (RPQ) formulae to compute more efficiently and accurately derivatives of 3-D FE solutions of electromagnetic problems. This new version of the RPQ formulae employ a reduced number of integration points leading not only to a drastic reduction of the computational effort but also to a substantial increase of accuracy. An accuracy test is presented in order to show the advantages of the new formulae, consisting of a remarkable enhancement of accuracy obtained with a reduced computational effort
