NAME
Gmsh - 3D finite element mesh generator with built-in CAD engine and
post-processor
SYNOPSIS
gmsh [file(s)] [option(s)]
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 visual-
ization capabilities.
Gmsh is built around four modules: geometry, mesh, solver and post-pro-
cessing. 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).
GEOMETRY OPTIONS
-0 Output model, then exit.
-tol float
set geometrical tolerance.
MESH OPTIONS
-1, -2, -3
perform 1D, 2D or 3D mesh generation, then exit.
-o file
specify output file name.
-format string
set output mesh format (auto, msh, msh1, msh2, msh4, unv, vrml,
stl, mesh, bdf, med, ...).
-bin

-clmin float
set minimum mesh element size.
-clmax float
set maximum mesh element size.
-rand float
set random perturbation factor.
-bgm file
