The development of HFSS

HFSS was the first general-purpose software product to solve arbitrary three-dimensional electromagnetic field problems. It introduced a number of new technologies in computational electromagnetics including automatic adaptive mesh generation, tangential vector finite elements, transfinite elements, and reduced-order modeling. This talk describes the early development of HFSS, the issues critical to its success, and some of the recent advances that enable HFSS to solve ever more complex problems quickly and accurately.
