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
	   use binary format when available.

       -saveall
	   save	all elements (discard physical group definitions)

       -algo string
	   select mesh algorithm (meshadapt, del2d, front2d,  del3d,  front3d,
	   hxt,	...).

       -parametric
	   save	nodes with their parametric coordinates.

       -part int
	   partition the mesh after batch mesh generation.

       -smooth int
	   set number of mesh smoothing	steps.

       -order int
	   set mesh order.

       -clscale	float
	   set global scaling factor to	the mesh characteristic	lengths	in the
	   model.

       -clmin float
	   Set minimum characteristic length.

       -clmax float
	   Set maximum characteristic length.

       -rand float
	   set random perturbation factor.

       -bgm file
	   load	the post-processing view in file  as  the  current  background
	   mesh.

       -check
	   perform various consistency checks on mesh.

POST-PROCESSING	OPTIONS
       -combine
	   combine input views into multi-time-step ones.

DISPLAY	OPTIONS
       -n  hide	all meshes and post-processing views on	startup.

       -fontsize int
	   specify the font size for the GUI.

       -display	string
	   specify display.

OTHER OPTIONS

       -pid
	   print pid on	stdout.

       -listen
	   always listen to incoming connection	requests.

       -v int
