I need so advise on SPH open source code to use to look at mergers and rotating objects... if anyone has some links or tutorials? Thank you!

I have a similar thought, suppose one have a rot expanded to inf. into to universe and for some reason the rod remains rigid and nothing obstructs it, on Earth we move the rod 1 degree, what would happen at the tip? answer exist...but isn't it a lovely day dream experiment.
