Abstract:

A numerical technique of the target-region locating(TRL)solver in conjunction with the wave-front method is presented for the application of the finite element method(FEM)for 3-D electromagnetic computation.First, the principle of TRL technique is described.Then, the availability of TRL solver for non-linear application is particularly discussed demonstrating that this solver can be easily used while still remaining great efficiency.The implementation on how to apply this technique in FEM based on magnetic vector potential(MVP)is also introduced.Finally, a numerical example of 3-D magnetostatic modeling using the TRL solver and FEMLAB is given. It shows that a huge computer resource can be saved by employing the new solver.
