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
       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  Output model, then exit.

       -tol float

       -parametric
           save nodes with their parametric coordinates.

       -part int
           partition the mesh after batch mesh generation.

       -smooth int

       -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

       -new
           create new model before merge next file.

       -merge
           merge next files.

       -open
           ppen next files.

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

       -pid

       -string string
           parse option string at startup.

       -option file
           parse option file at startup.

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