The COSY 8th Order Runge Kutta Integrator
AbstractWe studied simple example problems to compare the performance of
the COSY 8th order Runge Kutta integrator RK, and two of fourth order
Runge Kutta integrators; RK4 with fixed step size, and RK4S with
automatic step size control. The resulting low accuracy by the fourth
order integrators convinces us to urge to use high accuracy integrators for
modern computational needs.
