中文摘要：
流体-结构耦合问题广泛存在于各种工程领域，本文采用ALE显式有限元法求解该类问题，并对该方法的并行性进行讨论。同时根据流体-结构耦合问题与ALE显式有限元的计算特点，在坐标递归分区方法的基础上设计并程序实现了基于流体-结构耦合均衡的分区算法。通过与坐标递归分区方法的计算结果相比较，对于流体-结构耦合问题的求解，耦合均衡并行分区方法具有更好的加速比和并行效率。
英文摘要：
Fluid-structure interaction is applied widely in many fields of engineering. The problem is solved through explicit finite element method based on ALE description, which parallelism is analyzed simply. Meanwhile, based on the Recursive Coordinate Bisection, a fluid-structure interaction uniform bisection algorithm for domain decomposition is designed and implemented according to the characteristics of fluid-structure interaction and explicit finite element method. Comparing with Recursive Coordinate Bisection method, the interaction uniform bisection method has high speedup and parallel efficiency in solving fluid-structure interaction.
