| Research Abstract |
This research is aimed to construct the simulation system of tsunami while considering debris. The scope of the simulation covers the large-scale tsunami running up the ground supporting houses, buildings, and vehicles. The developed simulation is based on the SPH method (smooth particles hydrodynamics) solving the Navier-Stokes equations. The latest massive parallel computing technology was introduced to equations solver. Calculation speed is approximately increased about 10 times over the CPU computing. By the SPH method, both liquid (tsunami) and solid (debris) can be simultaneously simulated, which bring a possibility to evaluate the damage from both tsunami and debris attack that cannot be done by traditional simulation method.
