       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  Output model, then exit.

       -tol float
           set geometrical tolerance.


       -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, ...).

           use binary format when available.

           save all elements (discard physical group definitions)

       -algo string
           select mesh algorithm (meshadapt, del2d, front2d, del3d, front3d, ...).

           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.

           perform various consistency checks on mesh.


           combine input views into multi-time-step ones.


       -n  hide all meshes and post-processing views on startup.

       -fontsize int
           specify the font size for the GUI.

       -display string
           specify display.


       -   parse input files, then exit.

           create new model before merge next file.

           merge next files.

           ppen next files.

       -a, -g, -m, -s, -p
           start in automatic, geometry, mesh, solver or post-processing mode.

           print pid on stdout.

           always listen to incoming connection requests.

       -v int
           set verbosity level.

           don't popup dialog windows in scripts.

       -setnumber name value
           set constant number name=value

       -setstring name value
           set constant string name=value

       -string string
           parse option string at startup.

       -option file
           parse option file at startup.

       -convert files
           Convert files into latest binary formats, then exit.

           show version number.

           show detailed version information.

           show help message.
