This paper proposes an efficient potential and viscous flow decompositionmethod for wave-structure interaction simulation with single-phase potentialflow wave models and two-phase Computational Fluid Dynamics (CFD) solvers. Thepotential part - represents the incident waves - is solved with spectral wavemodels; the viscous part - represents the complementary perturbation on theincident waves - is solved with the CFD solver. This combination keeps theefficiency and accuracy of potential theory on water waves and the advantage oftwo-phase CFD solvers on complex flows (wave breaking, flow separation, etc.).The decomposition strategy is called Spectral Wave Explicit Navier-StokesEquations (SWENSE), originally proposed for single-phase CFD solvers. Firstly,this paper presents an extension of the SWENSE method for two-phase CFDsolvers. Secondly, an accurate and efficient method to interpolate potentialflow results obtained with the High Order Spectral (HOS) wave model on CFD meshis proposed. The method is able to reduce the divergence error of theinterpolated velocity field to meet the CFD solver's needs withoutreprojection. Implemented within OpenFOAM, these methods are tested by threeconvincing verification, validation and application cases, considering incidentwave propagation, high-order loads on a vertical cylinder in regular waves, anda Catenary Anchor Leg Mooring (CALM) buoy in both regular and irregular waves.Speed-ups between 1.71 and 4.28 are achieved with the test cases. The wavemodels and the interpolation method are released open-source to the public.
