M Order Continuous Finite Element Methods for Linear Hamilton Systems
【摘要】 利用常微分方程的连续有限元法证明了m次连续有限元算法能保持哈密尔顿系统的能量守恒。对线性哈密尔顿系统的m次连续有限元算法为辛算法,且能保持能量守恒,数值例子也验证了此结论。
【Abstract】 By taking advantages of the continuous finite element methods for ordinary differential equations,the m order finite element methods for linear Hamiltonian systems are proved to hold as well as conversation of energy.The method of symplectic algorithm maintains the energy for nonlinear Hamiltonian systems.The numerical examples given here are also argees with the theory.
