This paper discusses selected features of the Smoothed Particle Hydrodynamics (SPH) method when used in combination with a Finite Element (FE) software tool. Special attention is paid to the implementation of wall boundary conditions in view of their relevance to the simulation of fluid-structure interaction (FSI). Several industrial applications of the hybrid SPH-FE method are reviewed in detail. These include the ditching of a fixed-wing aircraft, the ditching of a helicopter with an Emergency Flotation System, and the flooding of a ship due to a breach in the hull. The comparison of the results of the numerical study on fixed-wing aircraft against experimental data demonstrate the validity of the SPH method. It is concluded that the SPH-FE approach is well-suited for the simulation of violent flow phenomena and fluid-structure interaction.

本文讨论了平滑粒子流体动力学 (SPH) 方法与有限元 (FE) 软件工具结合使用时的选定特征。鉴于壁边界条件与流固耦合 (FSI) 模拟的相关性，因此特别注意壁边界条件的实施。详细回顾了混合 SPH-FE 方法的几个工业应用。其中包括弃用固定翼飞机、弃用带有紧急漂浮系统的直升机，以及因船体破裂导致船舶进水。固定翼飞机数值研究结果与实验数据的比较证明了 SPH 方法的有效性。得出的结论是，SPH-FE 方法非常适合模拟剧烈流动现象和流固耦合。
