Abstract
To simulate free surface flows, various numerical methods can be used. One of these numerical schemes is Smoothed particle hydrodynamics which, as a Lagrangian method, has been considered by many of researchers to model violent free surface deformation. In the present article, an effort has been made to find how solitary wave generation can be simulated using SPH method, more accurately. WCSPH formulation was utilized, different time stepping algorithms were considered and the effects of density filter and smoothing length on simulated solitary wave, and wave breaking were studied. The obtained results were compared with other solutions existing in the literature. Based on the numerical findings, it is concluded that predictor-corrector scheme in conjunction with moving least square (MLS) density filter can give more accurate results. It was also indicated that number of time steps in which density filter must be performed, plays an important role in achieving favorable results.
