Outline of Final Research Achievements

In order to solve interaction between strongly nonlinear free-surface flows and structural dynamic responses, a numerical analysis method for fluid-structure interaction was developed by combining mesh-less particle methods and mesh-based finite element methods. The SPH method and the explicit MPS method which are adequate for large-scale simulation were adopted as the fluid solver, and a GPGPU code of each was used. As the FEM solver to be coupled with these particle methods, an open source “libMesh” which is capable for unsteady structural analysis was adopted. Although it is one way coupling, the fact that we could realize a fluid-structure coupled simulation by combining a large-scale particle method, which is applicable to realistic engineering problems, and FEM, would contribute to the future development of fluid-structure interaction analysis.
