This paper presents a CFD-FEA coupled co-simulation method for numerical prediction of ship hydroelastic response in regular waves. Two-way coupling of CFD and FEA solvers is applied where the external fluid pressure exported from the CFD simulation is used to derive the structural responses in the FEA solver and the structural deformations are fed back into the CFD solver to deform the mesh. The ship motions and vibrations are calculated in the FEM solver using the external fluid force and internal inertia force. Violent free surface flow such as slamming and green water on deck is well captured by the RANS and VOF techniques in the CFD solver. By conducting co-simulations with a standard S175 containership, the developed fully coupled method was proved to be capable and reliable in accurate simulating almost all the physical characteristics of interests within the scope of ship seakeeping and hydroelasticity. The typical results by the CFD-FEA method are also compared with these by a 3D hydroelasticity method based on potential flow theory.
