something to play with...
I recently found out, there is a program called "Comsol". It cost some serious $$$$$, but apparently it can do pretty much anything physics-related, mechanics, cfd, electrodynamics, acoustics, plasma physics, semiconductors, ..., and custom equations. And allows to tie all these disciplines into one problem. I'm slowly looking into attending a course, it looks like it can elevate engineering caps to a whole new level.
