目前波浪-结构相互作用的面板方法采用位势流理论，该理论为海洋结构提供了快速、可靠和相对准确的预测，现在有一些开源软件包，如NEMOH和HAMS。在本研究中，NEMOH和HAMS的相对效用和性能与著名的、最先进的软件WAMIT进行了比较。为了使这些比较得到关注，本研究基于三种不同的浮动结构：截断圆柱体；带升沉板的截尾筒体；以及一种新型多轴TALOS波能转换器。为了使比较更有用，本研究调查了简单圆柱体的不完整和重叠面板，以检查各自的代码是否可以处理这些问题并仍然提供有意义的解决方案。这些比较可以帮助我们了解不完整和/或重叠的面板是否可以用于简化这些非常复杂的海洋结构的数值模拟。从对比中可以看出，开源软件NEMOH和HAMS对于简单的单一海洋结构都能产生很好的结果，但在处理更复杂的海洋结构时表现出不同的能力。具体来说，它可以像WAMIT一样有效地处理薄结构和重叠面板。
Current panel methods for wave-structure interactions employ the potential flow theory, which provide fast, reliable and relatively accurate predictions for the marine structures, and now some open source packages, NEMOH and HAMS, are available. In this research, the relative utility and performance of NEMOH and HAMS is compared with the well-known, state-of-art software, WAMIT. To bring focus to these comparisons, this research is based on three different floating structures: the truncated cylinder; the truncated cylinder with heave plate; and a novel multi-axis TALOS wave energy converter. To make the comparison more useful, this research investigates the incomplete and overlapped panels for the simple cylinder, to examine whether the respective code can handle these and still provide a meaningful solution. The comparisons may help us to understand whether the incomplete and/or overlapped panels can be used for simplifying the numerical modelling of those very complicated marine structures. From the comparisons, it can be seen the open source software, NEMOH and HAMS, both could produce very good results for the simple single marine structure, but also exhibit different capacities in dealing with more complicated marine structures. Specifically, HAMS could handle the thin structures and the overlapped panels effectively as WAMIT.
