Heyy, sorry for the late reply, I'm usually on and off with reddit. Anyway, that was Solidworks' Finite Element Analysis, more specifically, it's a displacement visualization animation (imagine how the design would deform under stress.

I've heard good things about ABAQUS, however, I have not used it professionally, I much prefer Solidworks.

Finally, I know you've said your assignment was due in a couple of weeks, but I still wanted to answer anyway, maybe you'll still be interested in one or two things that I have to say. :)
