Holy crap! No, wait, it makes a HUGE difference just by changing the minimum and maximum to various values. This could keep me busy for a while.

Thank you Juergen! I think this is exactly what I was looking for.


Of course this doesn't model gravitation. Gravitational forces go with 1/r^2.

If you want to make a simulation a N-body problem with randomly placed masses also is very problematic, because if you use fixed time steps (delta t) then the model will break because when 2 masses come very close the steps will be to big and when you select smaller dt then you won't see anything.

I can post an example in a few minutes.

Therefore it would make sense to simulate just a few bodies with a fixed setup (like a planetary system)
