Abstract

A parallel numerical approach for electromagnetic transient analysis of grounding systems in frequency domain is presented. The iterative moments method based on conjugate gradient is employed to solve the numerical algorithm based on the discretization of electric field integral equation via thin-wire approximation. Advantages with respect to a direct moments method solution, already developed by the Authors, are discussed. 1 Introduction Various numerical techniques have been developed for the solution of electromagnetic fields problems and the method of moments (MM) has been applied successfully. This technique transform
