A fluid-structure coupling approach based on level set function is proposed in order to solve large deformation problems that are difficult to interface tracking method, such as ALE (Arbitrary Lagrangian-Eulerian) method. The fluid flow field is solved by using fixed mesh because the level set function can describe a complicated geometrical shape in analysis grids easily. In this study, kinematrical condition treatment with virtual particles is introduced at the fluid-structure interface and iterative computation based on a partitoned solution method is implemented.
