“…where Δt is the timestep size, u/Δx is its normal velocity divided by the distance between the cell centre and the centre of the neighbour cell. To avoid numerical convergency, the Co value should be restricted for different applications, such as less than 1 for relative mild flows and less than 0.3 breaking type flows (Huang et al, , 2021c. Therefore, the turbulence modelling strategy selection will dictate y + then link to overall mesh density and timestep choices, thus enormously influencing the computational costs.…”

“…In this way, both parts of the mesh are not distorted. This method is particularly used for cases with large motions to overcome the limitations of the dynamicMotionSolverFvMesh for those cases, such as a swinging WEC, large structural motions induced by rogue waves, planning hulls, or a water-entry process [45,97,98]. At the present stage, the overInterDyMFoam solver is used for overset simulations.…”

“…Corresponding mitigations may be seen in [100]. Another potential solution is to build the overset region sufficiently large to avoid communication locations near the area of interest [98], i.e. farther from the structure, which might help in predicting the fluid load/impact.…”

The modelling of wave-structure interaction (WSI) has significant applications in understanding natural processes as well as securing the safety and efficiency of marine engineering. Based on the technique of Computational Fluid Dynamics (CFD) and the open-source simulation framework - OpenFOAM, this paper provides a state-of-the-art review of WSI modelling methods. The review categorises WSI scenarios and suggests their suitable computational approaches, concerning a rigid, deformable or porous structure in regular, irregular, non-breaking or breaking waves. Extensions of WSI modelling for wave-structure-seabed interactions and various wave energy converters are also introduced. As a result, the present review aims to help understand the CFD modelling of WSI and guide the use of OpenFOAM for target WSI problems.
