<h2><a name="Description"></a>Description</h2>
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.
<p>

Gmsh's graphical user interface</a>, or the reference manual for a

<li>Gmsh imports STEP, IGES and BREP files thanks
to <a href="http://www.opencascade.org">OpenCascade</a>.
<li>Gmsh interfaces the following additional external mesh
generators: <a href="http://www.hpfem.jku.at/netgen/">Netgen</a> from
Joachim Schöberl
and <a href="http://tetgen.berlios.de/index.html">TetGen</a> from Hang
Si.
<li>Gmsh's high quality vector PostScript, PDF and SVG output is
produced by <a href="/gl2ps/">GL2PS</a>.
<li>Gmsh's cross-platform graphical user interface is based
on <a href="http://www.fltk.org/">FLTK</a>
and <a href="http://www.opengl.org/">OpenGL</a>.
<li>Make sure to also check out <a href="/getdp/">GetDP</a>, a rather
general finite element code that can be used right from Gmsh's
graphical user interface.
