I too have access to some basic CFD programs. The primary software program I have access to is CMARC (http://www.aerologic.com/cmarc.html
), which is better than the freebies, but getting the model loaded into the software is a pain and a half as all the points must be defined in text files (no CAD import).
The steig fuselage was designed in CFD and tested in the wind tunnel, at least according to the designers. Not sure how many iterations they went through.
