An efficient finite element method is presented to compute time harmonic microwave field in three dimensional configurations. Nodal-based finite elements have been coupled with an algorithm boundary condition to solve open boundary problems. Modeling real devices is made possible using parallel computation. This paper describes first the time harmonic formulation with the absorbing boundary condition and the sequential code. A new algorithm is then proposed to implement this formulation on a cluster of workstations (10 DEC ALPHA 300X). Analysis of efficiency is performed using simple problems. The electromagnetic scattering of a plane wave by a perfect electric conductor cylinder is finally given as example
