TI - Improved MPS-FE Fluid-Structure Interaction Coupled Method with MPS Polygon Wall Boundary Model T2 - Computer Modeling in Engineering \& Sciences PY - 2014 VL - 101 IS - 4 SN - 1526-1506 AB - The MPS-FE method, which adopts the Finite Element (FE) method for structure computation and the Moving Particle Simulation (MPS) method for fluid computation involving free surfaces, was developed to solve fluid-structure interaction problems with free surfaces. The conventional MPS-FE method, in which MPS wall boundary particles and finite elements are overlapped in order to exchange information at a fluid-structure interface, is not versatile and reduces the advantages of the software modularity. In this study, we developed a nonoverlapping approach in which the interface in the fluid computation corresponds to the interface in the structure computation through an MPS polygon wall model. The accuracy of the improved MPS-FE method was verified by solving a dam break problem with an elastic obstacle and comparing the result obtained with that of the conventional MPS-FE method and particle FEM.
