“…To that end, e.g. Elsafti and Oumeraci [19] or Li et al [20] propose different modelling frameworks, implemented in the open source CFD toolbox OpenFOAM ® . In these works, finite-volume method (FVM)-based quasi-steady models are applied to solve the physics of poro-elasticity and the numerical results are validated against experimental results of a standing wave-induced seabed response near a vertical wall.…”

Knowledge of the interaction between free surface waves and the seabed is required for the reliable design of marine structures, preventing severe structural failures. To that end, this paper presents the numerical modelling of wave-induced residual liquefaction of seabed soil. An OpenFOAM® finite volume solver is developed to simulate the behaviour of pore pressure and shear stress in the soil and is validated against analytical reference data. The soil is considered as a poro-elastic solid and an additional equation is solved for the pore pressure buildup. The governing equations are valid only up to the onset of liquefaction. A criterion based on the accumulated pore pressure is applied in order to predict the onset of residual liquefaction. The results show that the pore pressure and shear stresses are in good agreement with the analytical results and the relative errors are less than three percent. Also, the numerical results indicate that the wave induced residual liquefaction originates from the mudline and progresses slowly down the soil which is consistent with the analytical results. The pore pressure buildup for a seabed with stone columns shows that the liquefaction potential is very low near the stone column.

“…The incoming waves are simulated using the second‐order Stokes theory as implemented in the “waves2Foam” toolbox (Jacobsen et al., 2012) developed in the OpenFOAM framework. This toolbox has been successfully applied to simulate waves for multiphysics problems such as the wave–structure–seabed interaction (Li et al., 2018, 2020).…”

This work provides a novel approach that combines computational fluid dynamics (CFD) with computational solid mechanics (CSM) to dynamically simulate the fully coupled hydroelastic interaction between nonlinear ocean waves and a submerged horizontal plate breakwater (SHPB). Based on a systematic series of simulations, it is shown that the wave damping performance of an SHPB can be evidently improved by an appropriate extent of deformation, which can be achieved through the design of its bending stiffness by varying elasticity and/or aspect ratio. The wave attenuation effect is found to be maximized when an SHPB has a deformation amplitude close to the incident wave amplitude. By accounting for the hydroelastic effect through the fully coupled CFD+CSM approach, this work presents a new computational technique that supports the design of deformable offshore and coastal structures.

“…This method is meshless, which simplifies the solution of the seabed region and allows its application to larger configurations, such as around offshore pipelines Wang et al [107]. Li et al [84] developed an open-source numerical toolbox for modelling the porous seabed interactions with waves and structures in the finite-volume-method (FVM)-based OpenFOAM framework. This toolbox incorporates the incompressible Navier-Stokes equations for the wave module and the Biot equations for the seabed module considering the anisotropic seabed characteristics.…”

This review paper presents the recent advances in the numerical modelling of wave–structure–seabed interactions. The processes that are involved in wave–structure interactions, which leads to sediment transport and scour effects, are summarized. Subsequently, the three most common approaches for modelling sediment transport that is induced by wave–structure interactions are described. The applicability of each numerical approach is also included with a summary of the most recent studies. These approaches are based on the Reynolds-Averaged Navier–Stokes (RANS) equations for the fluid phase, and mostly differ in how they tackle the seabed response. Finally, future prospects of research are discussed.
