Wind engineering research is mainly based on wind tunnel test, numerical simulation and field measured three ways.
Numerical simulation can simulate real wind environment, the structures and buildings is actual size calculation model, compared with wind tunnel test, he avoided the scale and the actual wind environment.
And scholars believe that the wind speed based on the monte carlo method, time history curves for wind vibration analysis has limitations, thus put forward is based on the interference and random simulation method based on structural response.
With the rapid development of computational fluid dynamics (CFD), numerical simulation technology to get more extensive application.
But due to the civil engineering structure is a blunt body shape, wound flow with separation, attached again, vortex shedding and other complex flow phenomenon, and the wind field simulation of Gao Lei are provided for the technology is not mature, so the CFD numerical simulation is not confined to form complex structures.

These profiles are adopted as inlet profiles in Computational Fluid Dynamics (CFD) calculation[5].
The characteristics of velocity distribution of simulation from CFD match well with that of wind-drifted snow distribution got from the outdoor test in Haerbin.
