ALE (Arbitrary Lagrangian-Eulerian) moving mesh based schemes are the most frequently used as fluid-structure coupling approaches. However the ALE based methods are not suitable for tracking interfaces with large deformation and movement. In this study, an Eulerian fixed mesh with the level set function is adopted. A novel interface treatment using virtual particles with the level set function is proposed to treat kinematical condition at the interface. A partitioned strong coupling algorithm is constructed in order to combine the level set particle interface treatment and advanced fluid and structure solvers, i.e. CIP (Constrained Interpolation Profile) -FEM for fluid and MITC (Mixed Interpolated Tensorial Components) shell elements for structure. The interface treatment capacity is evaluated and an expanding airbag is analyzed.
