Double Pendulum

With Double Pendulum application you will be able to simulate problem a pendulum hanging from another pendulum situation. Its easy to make one, but its a pretty ferociously difficult mathematical problem, by most peoples standards. To even set up the relevant highly non-linear dual differential equations requires the formidable somewhat abstract mathematical machinery of Lagrangian Dynamics and Generalised Co-Ordinates. Surprisingly though, the program to solve these equations numerically using the improved Euler method is fairly short and simple (once I ironed out my algebraic errors, which are very easy to make).

Program keeps on running until you stop it. The Total Energy (Kinetic + Potential) should remain unchanged throughout the motion, but as time progresses the error in the calculations very slowly accumulates. This version is the first release on Softpaz Download.com.
