Coupled programming : Finite Elements - dynamical hysteresis flux tubes for non homogeneous circuit modeling
Résumé
A new dynamic modelling and simulation method of magnetic circuits using "dynamical hysteresis flux tubes" and "finite elementsn is presented. The "dynamical hysteresis flux tube" model can determine hysteresis loops of a material in case of homogeneous magnetic circuits. In order to increase the accuracy when an air-gap is introduced, we use a FEM near the air-gap area. The both methods can be coupled to obtain both the influence of material laws and local information in high gradient area. The aim of this paper is to present briefly the "dynamical hysteresis flux tuben model and the coupling method. The results will be compared with experimental values on a device designed for this purpose.
