Abstract: As a new method,the Level Set method had been developed to compute the interface of two-phase flow.The basic mathematical theory and the detailed method to solve the free surface hydrodynamic problem had been investigated.Then,by using the Level Set method,the transformation of a solitary wave over a front step was simulated.The results are in good agreement with laboratory experiments.
