提出了一种用各向异性高次有限六面体单元模拟薄壁结构的数值方法。通过对多项式次数的适当变化，找到了结构动力问题的有效离散化方法，并将其应用于流固耦合计算。给出了每个单元和方法的多项式次数的准最优选择，并用数值算例说明了其有效性。
A numerical approach to model thin-walled structures with anisotropic highorder finite hexahedral elements is presented. With an appropriate variation of the polynomial degrees an efficient discretization of a structural dynamic problem is found and then applied to a coupled fluid-structure interaction computation. Since a quasi-optimal choice of the polynomial degrees for every element as well as for method is presented and its effectivity is demonstrated with a numerical example.
