CONSTRUCTION OF SIMULATION SYSTEM OF FLOOD DISASTER USING AN OPEN SOURCE CFD TOOL AND A GAME ENGINE

Abstract

 In this study, we have developed a simulation system of the flood disasters such as sediment flood, tsunami, storm surge and so on, by using a game engine and a virtual reality device. To calculate the flood flow, we calculate the free surface flow based on the three-dimensional VOF method using OpenFOAM solver. In addition, we adopted the debris to the simulation system. The calculation of the motion of debris such as driftwood and rock are carried out using the physical engine of the game engine. By reflecting the motion of debris to the virtual reality space, a high-quality simulation of flood disasters has become possible.
