提出了一种基于增强扫描法的全自动壳体类结构高次六面体网格生成算法。传统的扫掠技术通过将初始单个表面网格沿指定轨迹沿着投影到指定目标表面来创建实体结构的全六面体单元网格。这里报道的工作增强了传统的薄固体方法,通过创建符合高阶全六面体有限元网格上的增强表面模型与表面相交的平行,垂直和斜角方向。新算法基于廉价的投影规则,将原始表面模型分成一组不相交的单表面和一个所谓的界面骨架。这个过程的核心是重塑初始曲面的边界表示,生成新的扫掠模板沿着相交曲线和连接在一个独立生成的界面网格的单扫掠六边形网格。
This paper presents a fully automated high-order hexahedral mesh generation algorithm for shell-like structures based on enhanced sweeping methods. Traditional sweeping techniques create all-hexahedral element meshes for solid structures by projecting an initial single surface mesh along a specified trajectory to a specified target surface. The work reported here enhances the traditional method for thin solids by creating conforming high-order all-hexahedral finite element meshes on an enhanced surface model with surfaces intersecting in parallel, perpendicular and skew-angled directions. The new algorithm is based on cheap projection rules separating the original surface model into a set of disjoint single surfaces and a so-called interface skeleton. The core of this process is reshaping the boundary representations of the initial surfaces, generating new sweeping templates along the intersection curves and joining the single swept hex meshes in an independently generated interface mesh.
