An Offline‐Based On‐Demand Visualization System of Large‐Scale Particle Simulation for Tsunami Disaster Prevention

SUMMARY After the Great East Japan Earthquake Tsunami, new Tsunami disaster‐prevention and mitigation methods for the next millennium Tsunami are actively being discussed. Consequently, the methods have highlighted the importance of both hard disaster‐prevention method, which means direct prevention using infrastructure such as breakwater, and soft disaster‐prevention method, including disaster‐prevention education. In this paper, a visualization and polygonization system that can be effectively utilized for Tsunami disaster prevention is proposed for large‐scale particle simulation. The system includes two important features, such as engineering‐purposed visualization and polygonization for hard and soft tsunami disaster‐prevention methods, respectively. Moreover, the system can handle the large‐scale particle simulation data that are computed by a high‐performance computer via an offline on‐demand tool without data transfer.
