WebMay 2, 2013 · Below is a specific implementation for solving equations of motion and other second order ODEs for physics simulations, amongst other things. To see it at work, there’s a demo below, or check out my elastic cursor trailer for a more complex version. The basic working behind the RK4 is to take snapshots of a particle’s motion as it travels. Webmethod (RK4) is very well suited for this purpose, as it is stable at large time steps, accurate and relatively fast. 2 Fourth order Runge-Kutta method The fourth order Runge-Kutta method can be used to numerically solve diﬁerential equa-tions.

WebIV. FOURTH ORDER RUNGE-KUTTA (RK4) Figure 3, which has a highly blown up scale on the vertical axis, shows that RK4 keeps the energy constant to very high precision. All in all, RK4isveryaccuratebut quite simple and so is the method of choice for many people. Combined with “adaptive stepsize control” (not necessary WebFor an example of this effect see this paper, which shows numerically unstable orbits of particle trajectories integrated by RK4 in a constant magnetic field (which should just go in circles). This is because RK4 is not even a volume-preserving transformation in x-px space (all symplectic transformations are volume-preserving, but not vice versa).
