Incompressible smoothed particle hydrodynamics (ISPH) method is a commonly used Lagrangian particle methods for free surface flow analysis. In this research, a partitioned coupling analysis system developed for numerical simulation of 3-dimensional FSI problems by adopting ISPH method and finite element method (FEM) has been employed. To evaluate the performance of this system toward large-scale problems, we demonstrated a dam-break problem with an elastic obstacle and compared the results calculated by this system and other methods.AN00349328第81回全国大会講演論文集201911011022019-02-282019-05-27
