Physics sims (In Progress)

Got the urge to do some physics simulations. Two scenarios I want to understand.

I) How does a lopsided spinning spaceship behave: SciFi scenarios have spaceships spinning on their axis to simulate gravity. How would a) it work with an asymmetric spaceship e.g. shaped like a hammer and b) how would it work with thrusters and attitude control, since we now have gyro forces.

II) Disintegrating body: Spinning body, say an asteroid, suddenly disintegrates. What does the debris field look like?

Discovered Project Chrono. It configures and compiles with no fuss. Just had to install eigen3 and irrlicht which were available on the Fedora repos. The demos work excellently, so will go ahead and see if I can code up the two simulations rattling inside my head.
