WebThe proposed quad-dominant mesh adaptation algorithm is based on simplicial optimization. It is driven by an anisotropic Riemannian metric and uses specialized local operators formulated in terms of an L ∞ instead of the usual L 2 distance. Furthermore, the physically-based vertex relocation operator includes an alignment force to explicitly … WebFlipping Cubical Meshes - We define and examine flip operations for quadrilateral and hexahedral meshes, similar to the flipping transformations previously used in triangular …

WebJun 4, 2024 · Very recently, a 36-element mesh was constructed by finding a sequence of flipping operations to transform the cube into Schneiders’ pyramid, interpreting each operation as the insertion of a hexahedron xiang36 . WebIn this paper we prove that the set of hex flipping transformations of Bern et. al. [1] is the only possible local modification on a geometrical hex mesh with less than 5 edges per vertex. We propose a new basis of local transformations that can generate an infinite number of transformations on hex meshes with less than 6 edges per vertex.
