“…The accurate description of wave kinematics is important for a number of applications, such as evaluating the kinetic wave energy, calibrating and validating the coupling of SPH with a computationally less expensive wave propagation model (Narayanaswamy et al, 2010;Abadie et al, 2012) or to investigate fluid loading on structures. The measured kinematics are compared with a set of non-linear, non-hydrostatic wave theories, aiming to predict theoretically the kinematics through a set of given wave parameters.…”

“…In the meantime, SPH may be coupled with a less computationally expensive wave propagation model, e.g. based on Boussinesqtype equations or other approaches (Narayanaswamy et al, 2010;Abadie et al, 2012;Altomare et al, 2014).…”

“…The information between the two solvers were transferred through a fixed boundary interface. Narayanaswamy et al [42] and Kassiotis et al [43] used the weak coupling of the Boussinesq model with the SPH method for solitary wave simulations without feedback from the SPH method to the Boussinesq model, a fixed overlapping zone was employed to transfer the information from the Boussinesq model to the SPH method.…”

This is the accepted version of the paper.This version of the publication may differ from the final published version. Permanent repository link AbstractThis is the first paper to present a hybrid method coupling a Improved Meshless Local Petrov Galerkin method with Rankine source solution (IMLPG_R) based on the Navier Stokes (NS) equations, with a finite element method (FEM) based on the fully nonlinear potential flow theory (FNPT) in order to efficiently simulate the violent waves and their interaction with marine structures. The two models are strongly coupled in space and time domains using a moving overlapping zone, wherein the information from both the solvers is exchanged. In the time domain, the Runge-Kutta 2 nd order method is nested with a predictor-corrector scheme. In the space domain, numerical techniques including 'Feeding Particles' and two-layer particle interpolation with relaxation coefficients are introduced to achieve the robust coupling of the two models. The properties and behaviours of the new hybrid model are tested by modelling a regular wave, solitary wave and Cnoidal wave including breaking and overtopping. It is validated by comparing the results of the method with analytical solutions, results from other methods and experimental data. The paper demonstrates that the method can produce satisfactory results but uses much less computational time compared with a method based on the full NS model.

“…The deep water wave model WAM, Shallow water wave model NSW and Boussinesq wave model BW is well established models and validated during several studies by others (Zeki and Okey, 2007;Narayanaswamy et al, 2010). Simulation of offshore wave penetration to inner harbor is very essential for evaluating harbor tranquility.…”
