Abstract: Various fluid structure interaction (FSI) models have been proposed in literature. FSI systems have been solved by simulating the fluid and structure either with solely mesh free or mesh-based methods. However, there are few researches that couple mesh free and mesh-based methods to interact fluid and structure. In the present study, a fluid structure interaction model is proposed in which fluid is simulated with Smoothed Particle Hydrodynamics (SPH) as a mesh free method and structure is simulated with a well-known mesh-based method (FEM). A well-known contact mechanic model is modified to simulate the interaction. In the model, water particles invading the solid domain are taken out of the solid structure by using the modified contact mechanics algorithm. The validations show that the proposed FSI model is promising. It should be noted that since the displacement of the structure should be very small in the experiments, structural displacements are not included in the present study
