If you want to calculate the structure of the accurate wind load, need to undertake building wind tunnel test, or simulate the structure of the wind load by using wind load CFD numerical.
If want to calculate the the accurate wind load of structure, need to undertake building wind tunnel test, or use wind load CFD numerical simulation the structure of the wind load.

Therefore, we can say that this domain has an excellent grid partition that can ensure the calculation precision of CFD.

Therefore, in this paper XFOIL was used to design preliminary airfoil, and then CFD tools were used to optimize and validate the airfoil.
However, accurate derivate can only achieved from CFD or wind tunnel, which have the disadvantage of intensive-calculation, high-cost, long-cycle, and aren’t fit for using in general design.

Analysis of the meshless method numerical simulation results The following numerical examples are used to analyze the results of the numerical simulation, in which the average error of the nodes value are mainly analyzed.
Besides, with the increasing of the influence domain radius, the simulation accuracy of m=2 and m=0 is improving, which describe that the size of the influence domain directly affects the accuracy of the simulation results.
Fig.3 shows the influence of the influence domain radius to the simulation results when the integral domain radius is 0.16667 and N=100.
Therefore, the influence domain increasing makes the average error to be stable. 2.4 The simulation of two-dimensional Poisson equation with derivative boundary condition using RPIM method (1) The simulation equation of the example is the same as 2.3, the numerical analysis is shown in Fig.4.

A numerical simulation is carried out to minimize the flow maldistribution inside the microchannel.
From the simulation results it was found that the mal-distribution is significantly affected by flow rate and shape of the header.
In the numerical simulation, it is identified that CFD is a suitable tool for predicting the flow distribution and for optimizing the design of the microchannel.
