In this paper we discuss the properties of the finite dimensional nonlinear systems relative to the numerical formulations of a class of three-dimensional electromagnetic field problems. These structural properties make us more confident on the results of the numerical calculations, since problems arising from multiple or even chaotic solutions are a priori excluded. Numerical procedures for the computation of transient and steady-state solutions are presented and applied. The error introduced by the finite element discretization is estimated making use of the properties of the dual electric and magnetic formulations.

Abstract
In this paper we discuss the properties of the finite dimensional nonlinear systems relative to the numerical formulations of a class of three-dimensional electromagnetic field problems. These structural properties make us more confident on the results of the numerical calculations, since problems arising from multiple or even chaotic solutions are a priori excluded. Numerical procedures for the computation of transient and steady-state solutions are presented and applied. The error introduced by the finite element discretization is estimated making use of the properties of the dual electric and magnetic formulations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
