"""Gmsh is a free 3D finite element grid 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 or in ASCII text
files using Gmsh's own scripting language.
