New Runge-Kutta algorithms are developed which determine the solution of a system of ordinary differential equations at any point within a given integration step, as well as at the end of each step.
本文创新性地提出了一种基于松弛技术和扩展Runge-Kutta Nystr?m(ERKN)方法的能量守恒算法,用于求解振荡哈密顿系统。通过引入松弛参数γ,新方法(RERKN)在保持原系统能量守恒性的同时,显著提升了长期数值模拟的精度。研究不仅证明了松弛参数的存在性,还 ...
