Abstract
The HFSS frequency domain computer code, installed on an AIX-3 computer, was used to model geometrically complex electromagnetic system operating over many decades of frequencies in non-homogeneous media. First, we used a single processor unit, and then 16 processors operating in parallel. Since the Maxwell equations used in the HFSS code show no time dependence, parallel processing can be conducted not only for the frequency but also for the time domain modeling (using Fourier transform).
