目前，德国的研究小组正在共同努力建立一个双向流固耦合问题的基准：一个几何非线性振动结构被不可压缩牛顿流体的层流搅动。在其他方法中，分区的解决方案程序已经开发在这个框架中使用高阶有限元代码耦合到一个格子玻尔兹曼求解器离散化流体的解决方案的结构侧。这两种完全不同类型的离散化的显式耦合给出了有希望的结果，也在一个有效的计算。本文简要介绍了该基准，介绍了使用的程序，并给出了应用该方法得到的一些结果。
Currently, a joint effort is made by German research groups to establish a benchmark for a bidirectional Fluid-Structure-Interaction problem: a geometrically non-linear vibrating structure being agitated by a laminar flow of an incompressible Newtonian fluid. Among other approaches, a partitioned solution procedure has been developed in this framework using a high order FEM code for the structural side of the solution coupled to a Lattice-Boltzmann solver discretizing the fluid. The explicit coupling of these two completely different types of discretizations gives promising results also in terms of an efficient calculation. This paper briefly introduces the benchmark, presents the procedure used and gives some results obtained by the application of the method.Copyright © 2006 by ASME
