提出了一种基于约束框架的棱柱网格生成方法,即利用物面网格节点与背景结构框架网格之间的单一映射关系线性插值生成棱柱网格。背景结构框架网格基于TFI方法生成。物面网格节点与背景框架网格之间的映射关系通过一种线性投影方法建立。然后通过V型槽、圆球、M6机翼和F6翼身组合体四种不同外形对该棱柱网格生成方法进行了测试,测试结果表明该方法能够避免棱柱网格生成中的网格交叉现象,保证棱柱网格的成功生成。该方法在棱柱网格质量控制、棱柱网格局部修改等方面具有较好的效率和优势,但背景框架网格的生成依然是该方法的一个瓶颈,需要进一步的研究。
A prism grid generation method based on constrained framework is proposed, which uses the single mapping relationship between object grid nodes and background structure grid to generate prismatic grids. Background Structure The frame grid is generated based on the TFI method. The mapping between object grid nodes and background frame grids is established by a linear projection method. Then, the method of generating the prism grid was tested by four different shapes of V-groove, sphere, M6 wing and F6 wing body assembly. The test results show that this method can avoid the grid crossing phenomenon in the prism grid generation , To ensure the success of the prism grid generation. This method has good efficiency and advantage in prism grid quality control and partial modification of prismatic grid. However, the generation of background grid is still a bottleneck of this method and needs further research.
