In this paper, we begin by recalling an adaptive mesh generation method governed by isotropic and anisotropic discrete metric maps, by means of the generation of a unit mesh with respect to aâ€¦ (More)

In this paper we present a general scheme suitable to optimize an arbitrary given surface triangulation representing a piecewise linear approximation of an underlying surface geometry The proposedâ€¦ (More)

This paper gives a procedure to control the size variation in a mesh adaption scheme where the size speci cation (the so-called control space) is used to govern the mesh generation stage. The methodâ€¦ (More)

Unstructured mesh adaptation is now widely used in numerical simulations to improve the accuracy of the solutions as well as to capture the behavior of physical phenomena. In this paper, we propose aâ€¦ (More)

This paper deals with the adaptation of unstructured meshes in three dimensions for transient problems with an emphasis on CFD simulations. The classical mesh adaptation scheme appears inappropriateâ€¦ (More)

Fast and accurate scanning devices are nowadays widely used in many engineering and biomedical fields. The resulting discrete data is usually directly converted into polygonal surface meshes, usingâ€¦ (More)

Geometric criteria, based on geometric feature analysis, are presented in this paper to deal with the evaluation of nite element surface meshes. Theoretical aspects as well as numerical examples areâ€¦ (More)

This paper proposes a method to evaluate the size quality as well as the shape quality of constrained surface meshes, the constraint being either a given metric or the geometric metric associatedâ€¦ (More)

Mesh adaptation is considered here as the research of an optimum that minimizes the P1 interpolation error of a function u of R given a number of vertices. A continuous modeling is described byâ€¦ (More)

To start, we recall a mesh generation method, allowing to create a so called unit mesh, which is an extension of the classical Delaunay method in the case where the process is governed via anâ€¦ (More)
