Description
Gmsh is a 3D 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. 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 or in ASCII text files using Gmsh's own
scripting language.
See the screencasts for a quick tour of
Gmsh's graphical user interface, or the reference manual for a
more thorough overview
of Gmsh's capabilities and some
frequently
asked questions.

- Gmsh imports STEP, IGES and BREP files thanks
to OpenCascade.
- Gmsh interfaces the following additional external mesh
generators: Netgen from
Joachim Schöberl
and TetGen from Hang
Si.
- Gmsh's high quality vector PostScript, PDF and SVG output is
produced by GL2PS.
- Gmsh's cross-platform graphical user interface is based
on FLTK
and OpenGL.
- Gmsh implements a ONELAB server to drive
external solvers, as for example the open source finite
solver GetDP.
- Gmsh and GetDP are bundled in the
Onelab/Mobile app for iPhone,
iPad and Android devices.
