I am working on a three body orbit problem. My equations have resulted in a beautiful 3D graph of the orbits, but only in one direction from t=0. (I have boundary conditions only for t=0). I can get the orbits for negative time by reversing all of the velocities, and I could combine the results to get a graph from negative time to positive time. Alternatively, I could use the results from the negative time calculations to become initial conditions for a new calculation, but these both seem like "klutsy" bandaids for the problem. Any suggestions? Allen Robnett
