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 or in ASCII text files
using Gmsh's own scripting language.
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, 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,
...).
-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

-merge
merge next files.
-open
ppen next files.
-a, -g, -m, -s, -p
start in automatic, geometry, mesh, solver or post-processing mode.
