| Outline of Final Research Achievements |
This study developed a numerical method for fluid-structure interaction problem due to tsunami wave impacts. The developed simulation method for tsunami propagation was based on VOF method for free surface moving boundary technique. And PDS-FEM based structure analysis method was developed for crack propagation of structure. And time history of wave force (pressure) data from tsunami propagation analysis method was implemented as external force of structure analysis to interact the wave force. Also, we developed solid-structure interaction analysis system to consider the deterioration of the structure from earthquake before tsunami coming. All systems developed in this study were carried out on K super parallel computer with good efficiency.
