摘要

网格生成对于获得基于网格的数值问题的精确而详细的解决方案至关重要,尤其是在捕捉域中指定区域内的特定信息时。虽然结构网格具有一致性,但其统一的分辨率限制了其实现一致性的能力。网格拉伸提供了一种解决方案,即在保留原始网格结构的同时,根据分析关系引入非均匀元素尺寸。本研究的目的是创建一个混合网格模型,充分利用结构网格和拉伸网格的优势。以带有肘形边缘的二维矩形为域。为了满足 CFD 应用的要求,通过增加边界和边角附近的元素密度来细化该域。然后对斜度、长宽比和元素质量进行评估,以确定整体网格质量。结果表明,拉伸结构化网格所产生的网格质量符合 CFD 域标准。

Stretched Meshing in a 2D Computational Domain with Elbow Edges for CFD Applications
Mesh generation is critical for obtaining accurate and detailed solutions to mesh-based numerical problems, particularly when capturing specific information within a designated area of the domain. While structured meshes offer consistency, their uniform resolution limits their ability to achieve this. Mesh stretching offers a solution by introducing non-uniform element sizes based on an analytical relationship while preserving the original mesh structure. The objective of this study is to create a hybrid mesh model that leverages the strengths of both structured and stretched meshes. A 2D rectangle with elbow edges serves as the domain. To address the requirements of CFD applications, the domain is refined by increasing element density near the boundaries and corners. Skewness, aspect ratio, and element quality are then assessed to determine the overall mesh quality. The results demonstrate that stretching the structured mesh produced a mesh with quality that meets CFD domain standards.
