我们比较了用于积分非线性 Klein-Gordon 方程 phitt-phixx+f(phi)=0 的四种显式有限差分格式的属性。事实证明,节能方案最适合研究解决方案的长期行为。对于没有空间依赖性的特殊情况也发现了相同的结果。
We compare the properties of four explicit finite difference schemes used to integrate the nonlinear Klein-Gordon equation ϕtt-ϕxx+f(ϕ)=0. It turns out that the energy conserving scheme is the most suitable to study the long time behavior of the solutions. The same result is found for the special case of no spatial dependence.
