A study on the parameters of an approach that combines the characteristic basis function method and the multilevel fast multipole algorithm is presented. This approach is a very efficient scheme for the rigorous computation of electrically large problems. An analysis of the configuration parameters of the method to obtain accurate results reducing CPU time is shown. Non-uniform rational B-splines surfaces are employed for the representation of the geometry and the characteristic basis functions are described in terms of curved rooftops generated in the parametric space. The associated macro-testing functions are defined as aggregations of curved razor-blade functions.
