A great advantage of QuickWave software is that new windows monitoring time-domain variation of the fields may be open at any time and set to any plane and any component. In some cases, the user may be interested in frequency-domain field magnitudes of just some components and in some sections. So far this has been possible via multiple runs at the selected frequencies. In version 6.0 a new Field Monitor postprocessing has been added. In pulse excitation regime, it Fourier-transforms time-domain fields at pre-selected frequencies, in-pre-defined planes. Example of application is shown in Section UG 2.5.1 and options for display control are described in Section S 2.4.1.
