Removing Local Irregularities of Triangular Meshes with Highlight Line Models

Bailin Deng

The highlight line model is a powerful tool in assessing the quality of a surface. It increases the flexibility of an interactive design environment. In this paper, a method to generate a highlight line model on an arbitrary triangular mesh is presented. B ...

Adaptive mesh refinement and automatic remeshing in crystal plasticity finite element simulations

Roland Logé

In finite element simulations dedicated to the modelling of microstructure evolution, the mesh has to be fine enough to: (i) accurately describe the geometry of the constituents; (ii) capture local strain gradients stemming from the heterogeneity in materi ...

Un modèle itératif de surface pour la construction en bois

Yves Weinand, Ivo Stotz, Gilles Gouaty, Eric Tosan

Dans le cadre de la construction en bois, nous nous intéressons à la modèlisation de maillages surfaciques 3D basés sur un modèle itératif inspiré du modèle IFS (Iterated Function System). Les formes modèlisées doivent satisfaire certaines propriétés afin ...

Parallel mesh adaptive techniques for complex flow simulation

Angelo Casagrande

Dynamic mesh adaptation on unstructured grids, by localised refinement and derefinement, is a very efficient tool for enhancing solution accuracy and optimise computational time. One of the major drawbacks however resides in the projection of the new nodes ...

Modélisation itérative de courbes et surfaces: aspect multi-résolution

Yves Weinand, Ivo Stotz, Gilles Gouaty, Eric Tosan

Nous présentons un modèle itératif de figures à motifs fractals. Ce modèle est exprimé dans un formalisme type IFS (Iterated Function System), qui est relié à l’approche par schéma de subdivision. Ce modèle itératif permet de définir des formes à pôles mul ...

Multiscale algorithm with patches of finite elements and applications

Vittoria Augusta Rezzonico Janka

We develop a discretisation and solution technique for elliptic problems whose solutions may present strong variations, singularities, boundary layers and oscillations in localised regions. We start with a coarse finite element discretisation with a mesh s ...

Geometric modeling based on triangle meshes

Mark Pauly

This course is designed to cover the entire geometry processing pipeline based on triangle meshes. We will present the latest concepts for mesh generation and mesh repair, for geometry and topology optimizations like mesh smoothing, decimation, and remeshi ...

Implicit meshes

Slobodan Ilic

This thesis proposes novel ways both to represent the static surfaces, and to parameterize their deformations. This can be used both by automated algorithms for efficient 3–D shape reconstruction, and by graphics designers for editing and animation. Deform ...

Adaptive finite elements with high aspect ratio for the computation of coalescence using a phase-field model

Marco Picasso, Alain Jacot, Erik Burman

A multiphase-field model for the description of coalescence in a binary alloy is solved numerically using adaptive finite elements with high aspect ratio. The unknown of the multiphase-field model are the three phase fields (solid phase 1, solid phase 2, a ...

Non-linear subdivision of univariate signals and discrete surfaces

Nicolas Aspert

During the last 20 years, the joint expansion of computing power, computer graphics, networking capabilities and multiresolution analysis have stimulated several research domains, and developed the need for new types of data such as 3D models, i.e. discret ...
