Abstract

This paper presents a 2D-3D hybrid method based on unstructured mesh for tsunami simulation. As a coupling method for the 2D and the 3D, the overlapping method using arbitrary grid has superior applicability for the wave transferring from bidirection. The 2D shallow water equation and the 3D Navier-Stokes equation are used as the governing equations. Several numerical examples are used to show the validity and the effectiveness of the presented method.
