摘要:
基于原始的带有旋转自由度的Allman单元,从转动分量定义出发,对原始的Allman单元泛函位能Ⅱp进行了一些修正,推导得到了一个新的单元.该单元成功地消除了Allman单元的主要缺陷--多余零能模式,同时保持了该单元的优点:列式简洁、精度高,给出的算例证实了改进单元的良好特性.
Abstract:
Based on the original Allman cell with rotational degrees of freedom, some modifications are made to the original Allman cell functional potential energy II.p from the definition of rotational components, and a new unit is derived. This unit successfully eliminates the main defect of the Allman unit - the redundant zero-energy mode, while maintaining the advantages of the unit: the column formula is concise, the accuracy is high, and the good characteristics of the improved element are confirmed by the given example.
