Abstract: An algorithm for coupling the smoothed particle hydrodynamics (SPH) method and the finite element method (FEM) is proposed for fluid–structure interaction (FSI) problems. The SPH module solves the fluid motion, and the FEM module describes the deformation of structures. In the algorithm, a structure is considered as a solid boundary in the SPH module and dealt with using the dynamic boundary condition. Only three layers of SPH boundary particles are set to represent the structure surface, and the interaction f… Show more

“…This allows for adaptability in scenarios where there are significant changes in particle position, as well as in cases of drastic interface change. The Langrangian particle properties of SPH enable the numerical solution to rely on various particle based solvers [26] , combined with appropriate constitutive and material models, which have good applicability for fluid, solid, and FSI simulations [27,28] . In many engineering fields, SPH has been widely used to solve free surface flow problems [29] .…”
