This is not a solution as the forward Euler becomes unstable with the
number of steps, too. I've had a perfectly settled system (i.e. in
static balance) explode in just a few dozen iterations. You have to
use a converging method, and the forward Euler is not one.

Sorry to be the bringer of bad news... please spare me :)
