Abstract
    The Relaxation Zone method (RZ) has been implemented in the meshless SPH-based DualSPHysics code. RZ acts as an internal wave maker and allows coupling DualSPHysics with any other model or analytical solution to generate sea waves. In this work, the coupling with the SWASH model is performed to simulate multi-scale and long-duration phenomena in coastal engineering, which represent a challenge for researcher and practitioners. In fact, despite the fact that SPH-based models are getting more and more popular in coastal and civil engineering, they still present a huge computational cost. In the present work, RZ is validated for phenomena of overtopping flow impacts on vertical walls. The results proved that the RZ is efficient and reliable alternative for wave generation in SPH-based models for coastal engineering applications.
