    INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN ENGINEERING Int. J. Numer. Meth.

Gmsh: a three-dimensional finite element mesh generator with built-in pre- and post-processing facilities Christophe Geuzaine1, Jean-Fran¸cois Remacle2∗ 1 Universit´ede Li`ege,Department of Electrical Engineering And Computer Science, Montefiore Institute, Li`ege, Belgium. 2 Universite´ catholique de Louvain, Institute for Mechanical, Materials and Civil Engineering, Louvain-la-Neuve, Belgium SUMMARY Gmsh is an open-source three-dimensional finite element grid generator with a build-in CAD engine and post-processor. Its design goal is to provide a fast, light and user-friendly meshing tool with parametric input and advanced visualization capabilities. This paper presents the overall philosophy, the main design choices and some of the original algorithms implemented in Gmsh. Copyright c 2009 John Wiley & Sons, Ltd. key words: Computer Aided Design, Mesh generation, Post-Processing, Finite Element Method, Open Source Software 1. Introduction When we started the Gmsh project in the summer of 1996, our goal was to develop a fast, light and user-friendly interactive software tool to easily create geometries and meshes that could be used in our three-dimensional finite element solvers [8], and then visualize and export the computational results with maximum flexibility. At the time, no open-source software combining a CAD engine, a mesh generator and a post-processor was available: the existing integrated tools were expensive commercial packages [41], and the freeware or shareware tools were limited to either CAD [29], two-dimensional mesh generation [44], three-dimensional mesh generation [53, 21, 30], or post-processing [31].

  • What Good Is a Linux Client?

    What Good Is a Linux Client?

    Preparing Today for Linux® Tomorrow What Good is a Linux Client? A Linux White Paper Preface Anyone who has followed the progress of Linux the past few years has noted the surprising gains that Linux has made in server operating system market share and “mindshare” against the entrenched opposition, notably Microsoft® Windows NT®, Novell Netware and various varieties of UNIX®. A complete Linux network, of course, would require Linux clients (networked PCs or terminals) as well. Therefore, an important question is, “Is Linux a viable desktop operating system for general business use?” or must we continue to be confined to the Windows world for our non-server needs? And what about laptop support, or a Small Office/Home Office (SOHO) user or home user, who does not need a network server? Is there a place for Linux in a stand-alone environment? These are some of the questions this paper addresses. I must confess that until recently I was merely a bystander watching with curiosity from the sidelines—without any real involvement— the progress Linux has made. So writing this paper not only gave me the excuse to join in on the action, but it also provides you with the perspective of a Linux “newbie” who is attempting to find the applications and utilities needed to create a working system. The conventional wisdom so far is that Linux is not “ready for prime time” as anything but a network operating system. We shall test this notion to see if I can find commercial, shareware and/or freeware programs for Linux to replace the existing applications I currently use with Windows.
