3d finite element mesh generator with built-in cad engine and post-processor
gmsh [file(s)] [option(s)]
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.
-0
parse all input files, output unrolled geometry, and exit.
-tol float
set geometrical tolerance.
-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.
-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.
-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.
-
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.
