Subject: Re: [TSSP] Modeling with ANSOFT
Hi Marco,
E-Tesla lays out the coil and various parts on an x-y grid and then
computes the resulting voltage profiles by long iterations. The C-code is
included with that, so maybe you could add the new parts you need and
recompile it without much trouble. You may also want to look at the BELA
E-field program:

It takes a little while to pick up on how the program works, but it is
super powerful and free ;-) It can do almost any 2-D situation. It may
distort the numbers some from a true cylindrical calculation but probably
pretty close.
Cheers,
Terry
