At present, the finite element method has become one of the most efficient and widely used numerical methods for solving various engineering problems. Its main power is mostly connected with its universality, simplicity and flexibility to be easy applied to various problems. Finally, recently, large-scale simulations based on the finite element method computation has become possible caused by improvements in the numerical calculation technology and computer performances. However, for highly complex, especially three - dimensional computations such as fluid dynamics or transient phenomenon, usually, a large computation time is still indispensable. Therefore, the speed-up of the computations for such CPU demanding problems is always analyst's desire Recently, various algorithms for speeding-up of the solutions of a large system of equations such as those generated by the finite element analysis has been proposed. Among them, the multigrid method[1]-[4] attract special interest due to their robustness generality, easy application and fast convergence rate. In this paper, we present an application of multigrid solution algorithm as an iterative solutions method for electromagnetic field computations.
