一种真实地形计算流体力学网格生成方法
A method for computational fluid dynamics grids formation on complex terrain
摘要
Abstract
As the applications of computational fluid dynamics(CFD) extend to the area of complex terrain simulations, it is important to systematically develop methods for CFD grids generation and optimization of complex terrains. Through a specific case study, a grid generation approach which contained steps of data acquisition, processing and conversion, construction of vertex, lines, faces and volumes,was presented. It was also stressed that the grid dependency study was important for choosing appropriate grids considering both the computation accuracy and costs. A suggestion of developing a software for complex terrain grids generation by redevelopment of current CFD preprocessors was also presented, which hopefully could enhance the grid generation efficiency significantly. The results show that the grid generated by this method agrees well with the complex terrain, and it could provide a solid foundation for CFD application in complex terrain simulations.关键词
