Coupling of Smoothed Particle Hydrodynamics with Finite Volume method for free-surface flows
A new algorithm for coupling meshless Lagrangian methods and Eulerian grid-based methods is proposed. A detailed validation using Smoothed Particle Hydrodynamics (SPH) and Finite Volume (FV) solvers is provided. To our knowledge this is the first time that a coupling like the present one is proposed, implemented and validated. We highlight how the intrinsic characteristics of both solvers can be exploited to efficiently and accurately resolve complex free-surface flows. The reported results clearly prove that the coupling strategy is convenient from the point of view of both accuracy and computing time.
