We present a software package that supports teaching different parallel programming models in a computational science and engineering context. It implements a Finite Volume solver for the shallow water equations, with application to tsunami simulation in mind. The numerical model is kept simple, using patches of Cartesian grids as computational domain, which can be connected via ghost layers. The...
Tsunami propagation in shallow water zone is often modeled by the shallow water equations (also called Saint-Venant equations) that are derived from conservation of mass and conservation of momentum equations. Adding friction slope to the conservation of momentum equations enables the system to simulate the propagation over the coastal area. This means the system is also able to estimate inundation...
Water simulation and terrain change are both important aspects in computer graphics and useful in producing realistic interactive environment. We present a step to combine the two phenomena together. In our system terrain is carefully organized to make it can be modified easily. The water flow is calculated by the shallow water simulation, which is a 2D simplification of Navier-Stocks equations. When...
