在蛙跳积分器中加入类能量守恒定律

Adding an energy-like conservation law to the leapfrog integrator

A. C. Maggs

摘要:

蛙跳积分器由于其良好的稳定性在分子动力学模拟中得到了广泛的应用。这被认为是由于方程的离散变分结构的存在。我们引入了一种改进的蛙跳方法,其中包括一个额外的能量一样的守恒定律嵌入一个分子动力学模拟在一个更大的动力学系统。

英文摘要:

The leapfrog integrator is widely used because of its excellent stability in molecular dynamics simulation. This is recognized as being due to the existence of a discrete variational structure of the equations. We introduce a modified leapfrog method which includes an additional energy-like conservation law by embedding a molecular dynamics simulation within a larger dynamical system.
