WebThis paper proves that the set of hex flipping transformations of Bern et. The modification of hexahedral meshes is difficult to perform since their structure does not allow easy local refinement or un-refinement such that the modification does not go through the boundary. In this paper we prove that the set of hex flipping transformations of Bern et. al. [1] is the … 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 …
