There are several outstanding programs around that can do this sort of
thing, but before sending you on a hunt for something that isn't what you need:
What coil design/performance information do you need? L? loss? coupling?
How accurately do you need the numbers? (10% good enough, or do you need
sub 1% accuracy?)
Is the coil closewound or spacewound (makes a difference in the amount of
"proximity effect"
for Rac... if the turns are spaced >5 times wire diameter, you can probably
ignore proximity effect and just use skin effect)
