Abstract :
The use of the impedance boundary condition in a finite element formulation is presented for high-frequency axisymmetric problems. The method has the following advantages: (a) a gain in discretization time; (b) a smaller system to be solved and thus a gain in computer memory; and (c) a gain in total computation time
