Gmsh - 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.
