| 摘 要： | 网格存在大变形时,传统的超限插值(TFI)动网格方法易于引起网格正交性问题.依据几何关系并考虑其插值特点,提出了一种带旋转修正的TFI动网格方法.对结构网格块进行分块,在子块角点间建立弹簧元,并基于弹簧类比法计算角点位移；子网格内部结点位移采用修正后的TFI动网格方法进行计算,从而形成具有弹簧-TFI混合特征的动网格新...

| Abstract: | Problems of orthogonal properties become more serious when the traditional transfinite interpolation(TFI) dynamic mesh method is employed for large deformations.Based on an analysis of the geometric relationship and interpolation features,an improvement for the present TFI method is proposed with a rotation correction.A new spring-TFI hybrid dynamic mesh method is developed for a structured mesh.First,each block of the computation domain is divided into several sub-blocks.Then,a spring network which connect... |
