Me too, I'm still being a bit of a dunce and can't find any material for muppets like me to bridge the math gap so I can understand how to apply the maths correctly myself but I can at least look at the pretty pictures. :)

I've just downloaded z88 so I can play with some FEA software, if I can outsource the clever bits to the computer I'm hoping I can get away with tweaking designs based on pretty colours...
