摘要
基于有限分析方法基础之上构造一种优化数值算法,阐述了该方法的基本理论和构 造过程,并对该数值方法进行稳定性分析。同时结合两个经典算例进行了计算和分析。结果 表明:该方法克服了有限分析系数中包含级数等计算复杂的缺点,能够消除数值弥散和振荡。
Optimization numerical algorithm is established based on finite analytic method. Basic theory and constructive process of this method and stability analysis are disussed. The results show that calculation complexity drawback of the order included in finite analytic coefficient can be got rid off. In addition, the method can avoid numerical divergence and oscillation, which proves its reliability and practicability.
