| Research Abstract |
Recently, risk of flood disasters, such as Tsunami and high tide, in coastal areas have been increasing because of the global warming, and flood disaster prevention and/or -reduction is one of the important issue. In Japan, many of the existing design codes for coastal structure are based on an experimental law aimed at vertical wall, and it is difficult to be directly applied the design code to arbitrary shaped structures. In this context, a new Fluid-Structure Interaction (FSI) simulator is necessary to improve the design code for coastal structures.
A FSI simulator by coupling an ISPH and the large deformed FEM is developed in this paper. In addition, we have developed a fast FEM solver for structural dynamics using a reduction method.
