Cell method and modified nodal method in eddy current electromagnetic problems

Abstract

This paper present an approximation of an electromagnetic eddy current problem in 2D coupled with circuital equations, using the Finite Formulation of Electromagnetics Fields and the modified nodal method. The definition equations of the two conductor models (filiform and solid types) are deducted with this formulation. The analysis is performed at steady state and transient state. To the transient state, a classical scheme of time discretization is used with the implicit Runge-Kutta method for two states. As validation method have been compared results between Finite Element Method and Finite Formulation of Electromagnetics Fields.
