Abstract

 A non-hydrostatic free surface numerical model is required to perform a tsunami inundation simulation. It is, however, difficult to carry out large-scale tsunami simulation because of the iterative calculation of the Poisson equation in the invompressible flow model.<br> In recent years, the Lattice Boltzmann Method (LBM) has attracted attention as a novel computational fluid dynamics to overcome the incompressible flow model problems. In this study, we developed a two-dimensional LBM for free surface simulation method based on Piecewise Linear Interface Reconstruction - Volume of Fluid (PLIC-VOF) method. The classical dam-break and reconstruction test is used to verify our approach enables to high accuracy free surface simulation compare to conventional LBM-VOF method.
