GMSH REFERENCE ARTICLE GENERATOR
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, and the freeware or shareware tools were limited to either CAD, two-dimensional mesh generation, three-dimensional mesh generation, or post-processing. 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, and then visualize and export the computational results with maximum flexibility. key words: Computer Aided Design, Mesh generation, Post-Processing, Finite Element Method, Open Source Software 1. This paper presents the overall philosophy, the main design choices and some of the original algorithms implemented in Gmsh. Its design goal is to provide a fast, light and user-friendly meshing tool with parametric input and advanced visualization capabilities. 2 Université 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.
