This paper presents a hybrid formulation using Whitney facet elements. This formulation is efficient for the modeling of unbounded 3-D magnetostatic problems. Boundary element method is used to model the unbounded regions and finite element method to model the ferromagnetic ones. Using equivalent circuit representation, the problem is changed, the degrees of freedom becoming magnetic flux in loops instead of faces. As a result, the dimension of the system to be solved is decreased.Index Terms-Boundary element method (BEM), facet finite elements, hybrid FEM-BEM, magnetostatics.

A volume integral formulation using facet elements to compute eddy currents in thin conductive shells is presented. The formulation is general and considers the field variation through the depth due to the skin effect. The formulation leads to an equivalent lumped elements circuit that can be coupled with an external circuit. The resolution of the circuit is achieved by the independent loops method. The formulation has been validated because of two numerical examples. Results are compared with an axisymmetric finite-element method (FEM) and another shell formulation implemented in a 3-D FEM.Index Terms-Eddy currents, facet element, generalized partial element equivalent circuit (PEEC) method, integral equation method, thin conductive shells.

An original and powerful volume integral formulation for solving electromagnetic problems is proposed. It is based on a facet interpolation for representing the magnetic flux in magnetic regions and the current density in conducting regions. This formulation is particularly well adapted for solving electromagnetic problems where air is preponderant, whatever the frequency. First results obtained are very encouraging, in terms of efficiency and accuracy.Index Terms-Electromagnetism, equivalent circuit, volume integral method (VIM), Whitney facet element.
