		<description>Thanks for sharing the mass spring damper system code.
I have been trying for years to simulate the motion of an engine valve using Runge Kutta but I don&#039;t know enough math or advanced coding to figure it out. Do you know if there is a diferrence in the answer between the the results you get and what the Runge method would return?

Like this?
