| Wind engineering calculation methods are also known as numerical wind tunnel, through the computer for numerical solution of the wind flow around the building followed by fluid dynamics equations, and can describe the image of simulation result making use of computer graphics technology to simulate of wind fields around the construction.Method of calculating the wind engineering of buildings are out of the shape and the surrounding environment, and can access to detailed, intuitive flow of information. Compared with wind tunnel tests, the performance of its advantages: 1. Low cost 2. fast Speed 3. Complete information, access to the entire wind field in the physical quantity (such as pressure, velocity, turbulent kinetic energy, etc.) So it can conduct a comprehensive analysis of the study 4. With the ability to simulate the real conditions, can create the same size and building a prototype computational model to simulate the actual wind environment, wind tunnel tests can be avoided as a result of effects caused by the size error. 5. It Can be set wider to simulate various conditions and has been successfully used for building the structure of the preliminary design stage.Numerical methods have broad prospect in the traditional wind tunnel tests of wind-tunnel which can not solve the issue, will continue to be accepted. In this paper, this method is the use in wind pressure distribution on buildingsThe main contents of this article:1. Elaborate the basic theory and knowledge elements of computational fluid dynamics on and introduce steps FLUENT software.2. Fluent software is used in square-shaped planar closed housing, a closed floor arched roof, sloping roof of a closed two-vector-type. Having numerical simulation of Vector-type coefficient and verifying the norms.3. The numerical simulation of the mean wind pressure coefficient using Fluent software for diamond-shaped saddle-shaped roof flat, flat oval and round saddle-shaped roof plane saddle-shaped roof for reference.
