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
       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.

GEOMETRY OPTIONS
       -0  parse all input files, output unrolled geometry, and exit.

       -tol float
           set geometrical tolerance.

MESH OPTIONS
       -1  perform the one-dimensional mesh, i.e., discretize all the curves
           in the geometry.

       -2  perform the two-dimensional mesh, i.e., discretize all the surfaces
           in the geometry.

       -3  perform the three-dimensional mesh, i.e., discretize all the
           volumes in the geometry.

       -part int
           partition the mesh after batch mesh generation.

       -saveall
           save all elements (and discard all physical group definitions).

       -o file
           specify mesh output file name.

       -format string
           set output mesh format (msh, msh1, msh2, unv, vrml, stl, mesh, bdf,
           p3d, cgns, med, fea).

       -bin
           use binary format when available.

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

       -smooth int
           set number of mesh smoothing steps.

       -optimize[_netgen]
           optimize quality of tetrahedral elements.

       -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.

       -clcurv
           Compute characteristic lengths from curvatures.

       -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
       -noview
           hide all views at startup.

       -link int
           choose link mode between post-processing views (0, 1, 2, 3, 4).

       -combine
           combine input views into multi-time-step ones.

DISPLAY OPTIONS
       -nodb
           suppress the double buffer. Use this options if you use Gmsh on a
           remote host without GLX.

       -fontsize int
           specify the font size for the GUI.

       -theme string
           specify the FLTK GUI scheme.

       -display string
           specify display.

OTHER OPTIONS
       -   parse input files, then exit.

       -a, -g, -m, -s, -p
           start in automatic, geometry, mesh, solver or post-processing mode.

       -pid
           print pid on stdout.

       -listen
           always listen to incoming connection requests.

       -v int
           set verbosity level.

       -nopopup
           don't popup dialog windows in scripts.

       -string string
           parse option string at startup.

       -option file
           parse option file at startup.

       -convert files
           Convert files into latest binary formats, then exit.

       -version
           show version number.

       -info
           show detailed version information.

       -help
           show help message.
