This paper presents a new monolithic formulation targeted at the simulation of fluid-structure interaction. It combines the dynamic version of the recent k-TMI extension of the Transfinite Mean Value Interpolation (TMI) of Dyken and Floater with the ALE formulation of the Navier-Stokes equations for moving finite element meshes along with the Lagrange multiplier method to accurately predict parietal shear. This new integrated k-TMI/ALE formulation is stable for the extreme case of zero mass ratios.

本文提出了一种针对流体-结构相互作用模拟的新型整体式配方。它结合了Dyken和Floater的超限均值插值(TMI)的最新k -TMI扩展的动态版本,以及用于移动有限元网格的Navier-Stokes方程的ALE公式,以及Lagrange乘数法,可以精确地预测顶面剪。这种新的集成的k -TMI / ALE配方对于零质量比的极端情况是稳定的。
