This article describes an improved paving method of automatic quadrilateral mesh generation. Paving, which was first proposed by Blacker and Stephenson [1 T. D. Blacker and M. B. Stephenson , Paving: A New Approach To Automated Quadrilateral Mesh Generation , Int. J. Numer. Meth. Eng. , vol. 32 , pp. 811 – 847 , 1991 .[Crossref], [Web of Science ®] , [Google Scholar]], is a kind of direct method for generating a quadrilateral mesh and has been widely used since it was presented. This article aims to improve some weaknesses of the traditional paving method by generating high-quality quadrilateral grids without employment of a background mesh. Through efficient intersection resolution and other optimization measures, the improved paving method can generate well-aligned rows of quadrilateral elements almost parallel to the boundary of the domain, automatically and quickly.
