N2 - In this study, the fluid-structure interaction (FSI) analyses utilizing the Incompressible Computational Fluid Dynamics (ICFD) solver implemented in LS-DYNA are performed. In addition, the accuracy verification not only of the fluid force calculation by water surface drop analyses using several wedge-shaped structures but also of the FSI analysis by a box-shaped structure is carried out. Assuming the bow flare slamming (BFS) behavior, the FSI analyses by the ICFD method of LS-DYNA on bow-shaped structures are also conducted. The differences of numerical results between the Arbitrary Lagrangian-Eulerian (ALE) method and the ICFD solver are investigated. The results show that the ICFD analysis gives the relatively reasonable values for time histories of fluid forces as well as pressure responses regardless of two-dimensional and three-dimensional structures. Through the comparison with theoretical values and empirical formulas, moreover, the discussions on the ICFD results are presented in detail.
