Journal ArticleDOI

Simultaneous untangling and smoothing of tetrahedral meshes

TL;DR: In this article, the authors proposed the substitution of objective functions having barriers by modified versions that are defined and regular on all R 3, which is also applicable to meshes with inverted elements, making a previous untangling procedure unnecessary.
Journal ArticleDOI

A new approach to solid modeling with trivariate T-splines based on mesh optimization

TL;DR: In this paper, the authors proposed a method to construct a trivariate T-spline representation of complex genus-zero solids for the application of isogeometric analysis, which only requires a surface triangulation of the solid as input data.
Journal ArticleDOI

An automatic strategy for adaptive tetrahedral mesh generation

TL;DR: A new automatic strategy for adaptive tetrahedral mesh generation using a local refinement/derefinement algorithm for nested triangulations and a simultaneous untangling and smoothing procedure are introduced.
Journal ArticleDOI

Genetic algorithms for an improved parameter estimation with local refinement of tetrahedral meshes in a wind model

TL;DR: The main goal of this work is the estimation of these parameters using genetic algorithms, such that some of the wind velocities observed at the measurement station are regenerated as accurately as possible by the model.
Journal ArticleDOI

Efficient refinement/derefinement algorithm of nested meshes to solve evolution problems

TL;DR: An adaptive refinement/derefinement algorithm of nested meshes is presented and its efficiency is shown through two numerical examples: a time-dependent convection-diffusion problems with dominant convection and a quasistationary problem.
