Method for calculating stress of arc plate breakwater structure

The present invention provides a method for calculating the stress of an arc plate breakwater structure. The method comprises: using the PLIC-VOF method to track the free surface of the fluid, and using the virtual boundary force method to simulate the mutual effect between the wave and the arc plate breakwater. Compared with the conventional method for calculating the stress of the arc plate breakwater, in the method provided by the present invention, the PLIC-VOF method is used to track the free surface of the fluid, and the position of the free surface of the fluid can be more accurately described; and the virtual boundary force method used in the method provided by the present invention does not require the boundary condition of the object plane to be arranged on the surface of the arcplate breakwater, so that the efficiency of numerical calculations can be significantly improved. 本发明提供种弧板式防波堤结构受力的计算方法，该方法利用PLIC-VOF方法追踪流体自由表面，利用虚拟边界力法模拟波浪与弧板式防波堤之间的相互作用；同传统的弧板式防波堤受力计算方法相比较，本发明利用PLIC-VOF方法追踪流体自由表面，能更加精确地刻画流
