We present several mixed methods to compute the eddy currents appearing at low frequency in multiply connected domains. They use a finite element method in the conductors and an integral formula in terms of fields on their boundaries. We compare CPU

We present and describe how a fixed-point method has been used to get an optimal computing for eddy currents. This work follows another one which was established some time ago and where we presented a new formulation in magnetodynamics; it has been d

We adapt the classical variational formulations in field h and in field e and also a mixed formulation in h and e in order to compute the eddy currents in a magnetic and/or laminated medium. The results obtained with the three formulations for the Jo

We present a mixed formulation for magnetostatics in unbounded domains. The magnetic flux density B is the principal unknown and it is interpolated with facet finite elements. The reduced scalar potential /spl phi/, which is considered as a Lagrange

We propose to compute the electric and magnetic fields e and h, in the case of magnetodynamics when the displacement currents are negligible, by means of a Boundary Integral Method (BIM) coupled to a Finite Element Method (FEM). For that, we first es

We consider a dielectric material, on the surface of which is applied a very thin conducting shell, which is submitted to a high frequency source field. We establish a variational formulation using integral equations in order to compute the tangentia

We compute the currents appearing in a circuit of very small thickness when a voltage is applied to its ends or when it is put into an inductive electric field. The discretization of the problem uses stream functions and then there is only one scalar

We present several formulations for the computation of the fields appearing In a conductor when it is immersed in a high frequency electromagnetic field. They all use a finite element method in the conductor but differ by the choice of the unknown qu

The two fields e-h formulation of magnetodynamics discretized with edge elements permits very easy computation of a posteriori local errors associated with the edges. This is used as a criterion to select the tetrahedra to be refined and we describe

The paper is devoted to an approximation of the solution of Maxwell's equations in three dimensional sapce. We present two methods which couple a finite element method inside the magnetic materials with a boundary integral method which uses Poincare-
