In the past 100 years, countless accident cases have shown that ship damage will directly pose a serious threat to personal and property safety. Therefore, research on important parameters such as water stability and sunk time of damaged ships has been the focus of industry research. Ship damage and water inflow is an extremely complicated process, involving the interaction of various factors such as hull movement, internal and external flow field and exchange, and it is difficult to establish an accurate theory based on its typical nonlinear flow  model, Due to the increasing maturity of computational fluid dynamics, it is not difficult to simulate the damage influent process. Many scholars have used FLUENT software to simulate it, which is consistent with the experimental comparison, indicating the feasibility of CFD for broken water. However, FLUENT relies on the characteristics of UDF and its single monitoring and setting complexity has been increasingly exposed. With the advent of STAR-CCM+, this defect is completely compensated, and its overlapping  modules in the motion module have greatly improved Grid quality and calculation speed.This paper briefly introduces the calculation process and makes theoretical preparations. Then based on the commercial software STAR-CCM+ and reference to the experimental results, the comparison between numerical simulation and experiment is carried out to verify the effectiveness of the calculation method.Then select a DTBT5415test model for foolding  process simulation.
