Hello,
My Name is Zaheer Ahmed, I am Doing Masters In computer Engineering, I am currently working on Comparison of Methods to solve N-Bodies Problem, Firstly i Start with Sun-Earth problem, using Leap Frog Method, the behavior of Earth was not correct, as it was not making complete rotation, then i tried Runga-Kutta 4th order Method, againg the behavior of Earth was not Correct, it was making semi-circle and coming back to the original position, i select DT (time step) as 0.1,0.01,0.001 and run the program but the result was same, then i moved to Earth-Moon problem, the result is again same, either i am doing some calculation mistake or i am not using the correct procedure to perform the simulation. When i am taking DT (time step) as 1 and running the program for 100000 steps, the result is correct but when i am entering the value (604800) time for one week it is giving error. Can Anyone Advice Me, where i am going wrong, as it is really important for me as i have to submit this project by the end of this month. I can provide you the results for my program, if anyone willing to help me plese reply me on zaheer.mujtaba at gmail.com. Waiting for your reply. Zaheer Ahmed
