Abstract
En 中文
PurposeThis paper aims to improve the quality of quadrilateral meshes by developing a method for cleaning and simplifying the topology structures generated by cross-field partitioning approaches, which significantly affect final mesh quality.Design/methodology/approachThe method extracts topology information from sub-regions obtained from streamline partitioning and establishes relationships among them. Slender quadrilateral blocks and short edges are first identified through intrinsic characteristics of the sub-regions. Virtual topology operations are applied to resolve identified problem features.FindingsThe method successfully identifies and resolves problematic features in block structures, including slender quadrilateral blocks, short edges, and limit cycles. Testing on various models demonstrates improved mesh quality, with results validated through comparison with automatically generated quad meshes using Ansys.Originality/valueThis research contributes a novel approach to topology cleaning in cross-field-based quadrilateral mesh generation, addressing a critical challenge in automated mesh generation.
