Meshing Tools

Gmsh

Gmsh is an open source 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 Application Programming Interface (API).

See this general presentation for a high-level overview of Gmsh and recent developments, the screencasts for a quick tour of Gmsh's graphical user interface, and the reference manual for a more thorough overview of Gmsh's capabilities, some frequently asked questions and the documentation of the C++, C, Python and Julia API.

The source code repository contains many examples written using both the built-in script language and the API (see e.g. the tutorials and the and demos).
