Abstract
In this study, the study of water waves was carried out using one of major the mesh-free CFD i.e. Smoothed Particle Hydrodynamics (SPH). DualSPHysics ver 5.0 which is an open-source SPH solver based on Weakly Compressible Smoothed Particle Hydrodynamics (WCSPH) was used to reproduce three dimension of water waves in large and medium numerical wave tanks (NWT). This study analyses water wave profiles and the accuracy of DualSPHysics for regular waves with period 1.15 second and two NWT were used, i.e., 35 and 15 m. In addition, advanced post-processing using VisualSPHysics was used to mimic water waves in real conditions. Single water depth was used, i.e. 0.4 meters for large and medium NWT. The results showed SPH has limitations for reproducing large NWT. However medium NWT successfully reproduce water wave with advanced post-processing using VisualSPHysics.
