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.
