In this study, a newly enhanced Fluid-Structure Interaction (FSI) model which incorporates mooring lines was used to simulate a floating structure. The model has two parts: a Computational Fluid Dynamics (CFD) model and a mooring model. The open-source CFD OpenFOAM® v1712 toolbox was used in the present study, and the convergence criteria and relaxation method were added to the computational procedure used for the OpenFOAM multiphase flow solver, interDyMFoam. A newly enhanced, tightly coupled solver, CoupledinterDyMFoam, was used to decrease the artificial added mass effect, and the results were validated through a series of benchmark cases. The mooring model, based on the finite element method, was established in MATLAB® and was validated against a benchmark analytical elastic catenary solution and numerical results. Finally, a model which simulates a floating structure with mooring lines was successfully constructed by connecting the mooring model to CoupledinterDyMFoam.

在这项研究中，新增强的流固耦合 (FSI) 模型结合了系泊缆绳，用于模拟浮动结构。该模型由两部分组成：计算流体动力学 (CFD) 模型和系泊模型。本研究使用开源 CFD OpenFOAM® v1712 工具箱，并将收敛标准和松弛方法添加到用于 OpenFOAM 多相流求解器 interDyMFoam 的计算程序中。新增强的紧耦合求解器 CoupledinterDyMFoam 用于减少人为增加的质量效应，并通过一系列基准案例验证了结果。系泊模型基于有限元方法，在 MATLAB® 中建立，并根据基准解析弹性悬链线解和数值结果进行验证。最后，
