To generate a computational grid around a geometry easily and calculate a flow field with high order of accuracy helps to understand a flow field. However, the ease of the grid generation and the accuracy of the calculation are usually inconsistent. In this paper, to make a three-dimensional grid easily and efficiently, the grid generation method with a cartesian grid around a three-dimensional complex geometry was proposed to accelerate the computational grid generation process and a grid generation time was reduced to half. Furthermore, by making clear the relation between the accuracy of the computation and the grid property such as the minimum grid spacing and the dense of the grid, it was proved the latter is much more effective to the accuracy of the computation. | |||||
