Webb4 maj 2016 · The Runge-Kutta Method is a numerical integration technique which provides a better approximation to the equation of motion. Unlike the Euler's Method, which calculates one slope at an interval, the Runge-Kutta calculates four different slopes and uses them as weighted averages. These slopes are commonly referred as k1, k2, k3 and … WebbThe Fourier pseudo-spectral method is employed in spatial discretization and the symplectic Runge–Kutta method is utilized for the resulting semi-discrete system to arrive at a high-order fully discrete scheme. Simultaneously, the conservation of the original multiple invariants for the schemes are rigorously proven.
