Actually, FastModel is free. However, its license does expire from time to time. If this bothers you, we can provide you a permanent license.
This can be for free as well if you buy one or more FasterCap licenses.
If you instead are interested only in FastModel, please contact me directly at s.u.pp.or.t <at> fastfieldsolvers.com (remove the dots and replace <at> with @; the email address is garbled for fooling spam robots), so I'll be able to provide you a customized offer.
