I'm big on EM simulations now since its become my hobby.  But at work, I
naturally rely on intuition and bench experiments.  If that doesn't
work, then I fall back to Agilent ADS or something similar.  I was just
very curious about how EM simulators worked.  Now I'm sucked in to it. 
Its a natural marraige of programming and electronics.  I've been really
hoping my web site would get more hams and experimenters interested in
it.  You really need a knowledge of vector calculus to get deep into it,
but in numerical methods, a lot of the esoteric stuff from math class
turns into addition, multiplication, and other simple formulas, so its
not that bad.  FDTD is a perfect example.
