What step sizes are you using? What method are you using?
For me to get the program to work I used Runge-Kutta with step size 0.01.
If you are using larger step size, then you are probably not going to
converge to an answer. If you are using a more naive method, like Forward
Euler, then your step size should be significantly smaller (I'm not sure
if Forward Euler will work).
