The solution of fluid computer based on N-S equations is the core of Computational Fluid Dynamics (CFD), and Finite Volume Method (FVM) is the computational method of the main stream of fluid.The grid technology closely related to CFD is only a foundation, and it becomes more and more lagging with the development of CFD in iphone 13 price ohio computer.But grid is the most important and indispensable part.For the fluid aerodynamic simulation computation, the grid section is popular now hexahedral meshing method, the meshing time of some complex models tends to account for about 90% of total amount control.Although it is the basic work, the proportion of the workload is large amounts.

Therefore, the parametric modeling can substantially reduce some unnecessary modeling gymnastics wall decals time.For parametric modeling, VB, VC and other programming languages are generally used to parametric development model.Now a great number of commercial software that has integrated this function has no use for additional development.In this paper, the parametric functions are applied to the simulation model in the design, focusing on the analysis of parameterized system design script problems, which were liable to occur for the correction projectile and other related ammunition aerodynamic design provides a good research ideas.
