Yes, that's exactly what I meant. Leap frog is just some kind of Runge Kutta
(which is also a numerical solution to differential equations), but it's
faster and it's reversible. I have programmed (as most physic students) a
Runge Kutta of order 4 to simulate planetary movement. Later we have used
same algorithm for gas simulation with 100 particles. But Leap Frog should
be better for this purpose for speed reasons. Any forces should be possible.

I would prefer external program in C. Also for speed reasons.
Thanks for reply,
