【Abstract】 In this paper,a new method of the computational domain decomposition and the grid discretization in Computational Wind Engineering(CWE) is firstly proposed based on the research findings on the equilibrium atmospheric boundary layer and the practical experience.It aims to realize the sharing of the numerical models for the case of different wind attack angles and reduce the repeating work in model construction.By employing it,the efficiency of numerical simulation is highly improved.Secondly,the modeling of the equilibrium atmospheric boundary layer based on this new method is numerically verified and no extra numerical error is introduced.At last,the applicability of this method to the practical use is numerically verified.It might be helpful to achieve the automatic numerical model construction and analysis by employing this new method.更多还原
