Based on the boundary element method (BEM), the waterexit problem of 2D body was simulated to analyze the hydrodynamic force phenomenon. It was assumed that the fluid was incompressible and inviscid, the structure was rigid and waterexit vertically at constant speed. Lagrange grid was adopted to track the motion of every node and the change of velocity potential, the nonlinear free surface during the process of waterexit was calculated. Results show that when a body approaches the free surface, the upper free surface will generate upwelling area, and the hydrodynamic pressure down into the water encountered by the structure will increase significantly.
