Isotropic 2D Quadrangle Meshing with Size and Orientation Control

By Bertrand Pellenard, Pierre Alliez and Jean-Marie Morvan

Abstract

18 pagesInternational audienceWe propose an approach for automatically generating isotropic 2D quadrangle meshes from arbitrary domains with a fine control over sizing and orientation of the elements. At the heart of our algorithm is an optimization procedure that, from a coarse initial tiling of the 2D domain, enforces each of the desirable mesh quality criteria (size, shape, orientation, degree, regularity) one at a time, in an order designed not to undo previous enhancements. Our experiments demonstrate how well our resulting quadrangle meshes conform to a wide range of input sizing and orientation fields
