Seamless Global Parametrization in a Single Optimization

Autor: Coiffier, Guillaume, Corman, Etienne

The challenge of computing high quality seamless parametrizations is to account for both the optimal placement of singularity cones and distortion minimization. Existing methods rely either on greedy solvers or on a simplified two steps problem, firs

All-Hex Meshing Strategies for Densely Packed Spheres

Autor: Lan, Yu-Hsiang, Fischer, Paul, Merzari, Elia, Min, Misun

We develop an all-hex meshing strategy for the interstitial space in beds of densely packed spheres that is tailored to turbulent flow simulations based on the spectral element method (SEM). The SEM achieves resolution through elevated polynomial ord

We present a new fully automatic block-decomposition algorithm for feature-preserving, strongly hex-dominant meshing, that yields results with a drastically larger percentage of hex elements than prior art. Our method is guided by a surface field tha

Volumetric decomposition is essential for all-hexahedral mesh generation. Because fully automatic decomposition methods that can generate high-quality hexahedral meshes for arbitrary volumes have yet to be realized, manual decomposition is still requ

International audience; We propose a robust pipeline that can generate hex-dominant meshes from any global parameterization of a tetrahedral mesh. We focus on robustness in order to be able to benchmark different parameterizations on a large database
