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,  in ASCII text files using Gmsh's own scripting language (.geo
       files), or using the C++, C, Python or Julia Application Programming Interface (API).

GEOMETRY OPTIONS

       -0  Output model, then exit.

       -tol float
           set geometrical tolerance.

MESH OPTIONS

       -1, -2, -3

       -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
