Light and easy 3D mesh CAD design software featuring post-processing and a collection of modules with its own scripting language.

Gmsh is a free and open source CAD designer app and 3D editor developed by Christophe Geuzaine and Jean-Francois for Windows. It's portable, advanced, well-designed, user friendly and light on system resources.

The download has been tested by an editor here on a PC and a list of features has been compiled; see below. We've also created some screenshots of Gmsh to illustrate the user interface and show the overall usage and features of this CAD designing program.

3D finite element mesh generator with processing facilities

Gmsh is a free 3D finite element mesh generator with a built-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. Gmsh is built around four modules: geometry, mesh, solver and post-processing. The specification of any input to these modules is done either interactively using the graphical user interface, in ASCII text files using Gmsh's own scripting language (.geo files), or using the C++, C, Python or Julia API.
