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.
