Adaptive mesh coarsening for quadrilateral and hexahedral meshes
Finite Elements in Analysis and Design, 2010Mesh adaptation methods can improve the efficiency and accuracy of solutions to computational modeling problems. In many applications involving quadrilateral and hexahedral meshes, local modifications which maintain the original element type are desired. For triangle and tetrahedral meshes, effective refinement and coarsening methods that satisfy these

Equivalence of several quadrilateral shape regular mesh conditions used in finite element analysis are proved and their influence on the finite element interpolation error studied. The necessity of the bisection condition is emphasized through illustrations.

The authors consider three degenerate mesh conditions, namely, the conditions of \textit{P. Jamet} [SIAM J.Numer. Anal. 14, 925--930 (1977; Zbl 0383.65009)], \textit{G. Acosta} and \textit{R. G. Duran} [SIAM J. Numer. Anal. 38, 1073--1088 (2000; Zbl 0981.65124)], and \textit{E. Süli} [Math. Comput. 59, 359--382 (1992; Zbl 0767.65072)].

Angle-Preserving Quadrilateral Mesh Parameterization
IEEE Computer Graphics and Applications, 2015In response to their growing use in the real world, this article presents two algorithms for direct parameterization of quadrilateral meshes. The proposed algorithms are angle-preserving mappings, with one mapping a topological disk surface onto a Euclidean plane and one mapping a topological sphere surface onto a unit sphere.

CONSTRAINED QUADRILATERAL MESHES OF BOUNDED SIZE
International Journal of Computational Geometry & Applications, 2005We introduce a new algorithm to convert triangular meshes of polygonal regions, with or without holes, into strictly convex quadrilateral meshes of small bounded size. Our algorithm includes all vertices of the triangular mesh in the quadrilateral mesh, but may add extra vertices (called Steiner points). We show that if the input triangular mesh has t

v2 Subdivision for quadrilateral meshes
The Visual Computer, 2004This paper presents a $\sqrt2$ subdivision scheme for quadrilateral meshes that can be regarded as an extension of a 4-8 subdivision with new subdivision rules and improved capability and performance. The proposed scheme adopts a so-called $\sqrt2$ split operator to refine a control mesh such that the face number of the refined mesh generally equals ...
