Abstract
This paper presents a simulation based experience system in evacuation building using OpenFOAM and VR device. To estimate tsunami propagation and forces against a building, 3-D simulation based on VOF method which involves the OpenFOAM solver was applied. Study of aperture ratio of building was carried out to compare tsunami forces around building and inundation of each floor inside building. These results can be shown the validity of not only planning for building design but also education and training for disaster prevention.
