“…Wave breaking and wave-structure interaction are both very complex phenomena, but interFoam has also been utilized to simulate more simple cases, such as the progression of a solitary wave by Wroniszewski et al (2014), which was suggested as a benchmark to compare to other CFD codes. The study by Wroniszewski et al (2014) highlighted a problem, that to our knowledge, has gone largely unnoticed in the formal journal literature, namely that the velocity at the crest of the wave is over-predicted relative to the analytical solutions. This was also highlighted in conference paper Roenby et al (2017b), the MSc thesis of Afshar (2010) and the PhD thesis Tomaselli (2016).…”

The performance of interFoam (a widely-used solver within the popular open source CFD package OpenFOAM) in simulating the propagation of a nonlinear (stream function solution) regular wave is investigated in this work, with the aim of systematically documenting its accuracy. It is demonstrated that over time there is a tendency for surface elevations to increase, wiggles to appear in the free surface, and crest velocities to become (severely) over estimated. It is shown that increasing the temporal and spatial resolution can mitigate these undesirable effects, but that a relatively small Courant number is required. It is further demonstrated that the choice of discretization schemes and solver settings (often treated as a "black box" by users) can have a major impact on the results. This impact is documented, and it is shown that obtaining a "diffusive balance" is crucial to accurately propagate a surface wave over long distances without requiring exceedingly high temporal and spatial resolutions. Finally, the new code isoAdvector is compared to interFoam, which is demonstrated to produce comparably accurate results, while maintaining a sharper surface. It is hoped that the systematic documentation of the performance of the interFoam solver will enable its more accurate and optimal use, as well as increase awareness of potential shortcomings, by CFD researchers interested in the general CFD simulation of free surface waves.

Summary Three numerical methods, namely, volume of fluid (VOF), simple coupled volume of fluid with level set (S‐CLSVOF), and S‐CLSVOF with the density‐scaled balanced continuum surface force (CSF) model, have been incorporated into OpenFOAM source code and were validated for their accuracy for three cases: (i) an isothermal static case, (ii) isothermal dynamic cases, and (iii) non‐isothermal dynamic cases with thermocapillary flow including dynamic interface deformation. Results have shown that the S‐CLSVOF method gives accurate results in the test cases with mild computation conditions, and the S‐CLSVOF technique with the density‐scaled balanced CSF model leads to accurate results in the cases of large interface deformations and large density and viscosity ratios. These show that these high accuracy methods would be appropriate to obtain accurate predictions in multiphase flow systems with thermocapillary flows. Copyright © 2016 John Wiley & Sons, Ltd.

“…The presence of spurious currents near the free surface has been reported by other authors in the cases of both surface tension driven flows and gravity driven flows [3,10,31,32]. Especially, in a solitary wave simulation by Wroniszewski et al [11], it is shown that the spurious currents around the free surface were developed not only with OpenFOAM code but also in the cases of Gerris and Thétis. The reason for such behavior is believed to arise from an imbalance in the discretized momentum equation near the free surface and may explain the decreasing wave periods and increasing wavelengths in the interFoam simulation.…”

“…Simulations of regular waves using STAR-CCM+ software [8] and interFoam solver [9,10] demonstrate that the simulated surface elevations are sensitive to the temporal and spatial resolution, decreasing wave heights and phase shifts are observed in those cases with large time steps and coarse grids. The velocity profiles along the vertical cross-section are also examined by some authors [10,11], severely overestimated velocities are found near the free surface not only in interFoam simulations but also in the solutions with other Navier-Stokes solvers, including Gerris and Thétis.…”

The performance of interFoam (a widely used solver within OpenFOAM package) in simulating the propagation of water waves has been reported to be sensitive to the temporal and spatial resolution. To facilitate more accurate simulations, a numerical wave tank is built based on a high-order accurate Navier-Stokes model, which employs the VPM (volume-average/point-value multi-moment) scheme as the fluid solver and the THINC/QQ method (THINC method with quadratic surface representation and Gaussian quadrature) for the free-surface capturing. Simulations of regular waves in an intermediate water depth are conducted and the results are assessed via comparing with the analytical solutions. The performance of the present model and interFoam solver in simulating the wave propagation is systematically compared in this work. The results clearly demonstrate that compared with interFoam solver, the present model significantly improves the dissipation properties of the propagating wave, where the waveforms as well as the velocity distribution can be substantially maintained while the waves propagating over long distances even with large time steps and coarse grids. It is also shown that the present model requires much less computation time to reach a given error level in comparison with interFoam solver.
