We have developed a SPH based Fluid-Structure Interaction (FSI) model to compute hydrodynamics around structures such as wave-dissipating blocks. To improve the accuracy of FSI simulation, we carefully investigate the neighboring search of the water and solid particles, labeling of solid particles, selection of kernel function. We also formulated and added frictional forces between solids required for designing structures composed of wave-dissipating blocks. The present model was validated with dam-break wave, beam vibrations, static friction, and the interaction between an elastic plate and fluid. The results are compared with previous research and analytical solutions, and showed reasonable accuracy in gravitational wave propagation, static frictional forces and the maximum displacement of elastic bodies.
