On the coupling of the generalized multipole technique with the finite element method

It is shown how the coupling of the generalized multipole technique (GMT) with the finite-element (FE) method can enhance the advantages of both technique sand help to overcome their specific weaknesses. The FE technique allows the simulation of nonlinear and anisotropic materials and the GMT allows the simulation of all the linear paths of the problem even for regions of infinite extent with fewer unknowns than the usual methods. A few examples which show the benefits of the joint technique are presented. Particular attention is given to the calculation of a nonlinear coil.<
