Gmsh is an open source 3D finite element mesh generator with a built-in CADengine and post-processor. Its design goal is to provide a fast, light anduser-friendly meshing tool with parametric input and advanced visualizationcapabilities. Gmsh is built around four modules: geometry, mesh, solver andpost-processing. The specification of any input to these modules is done eitherinteractively using the graphical user interface, in ASCII text files usingGmsh's own scripting language (.geo files), or using the C++, C,Python or Julia Application Programming Interface (API).
See this general presentation fora high-level overview of Gmsh and recent developments,the screencasts for a quick tour of Gmsh's graphicaluser interface, and the reference manual fora more thorough overview ofGmsh's capabilities,some frequently askedquestions and the documentation ofthe C++, C, Python and Julia API.
The source code repositorycontains many examples written using both the built-in script language and theAPI (see e.g. thetutorialsand theand demos).

- Gmsh uses OpenCascade for constructive geometry features, and interfaces the optional external mesh and mesh adaptation librairies Netgen and Mmg3d.
- Gmsh's cross-platform graphical user interface is based on FLTK and OpenGL.
- Gmsh's high quality vector PostScript, PDF and SVG output is produced by GL2PS.
- Gmsh implements a ONELAB server to drive external solvers such as the open source finite element solver GetDP. Gmsh and GetDP are bundled in the ONELAB app for iPhone, iPad and Android devices.

Gmsh is built around four modules: geometry, mesh, solver and post-processing. All geometrical, mesh, solver and post-processing instructions are prescribed either interactively using the graphical user interface (GUI) or in text files using Gmsh's own scripting language. Interactive actions generate language bits in the input files, and vice versa. This makes it possible to automate all treatments, using loops, conditionals and external system calls.
