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 mesh 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 flexible
visualization capabilities.
Gmsh is built around four modules (geometry, mesh, solver and post-processing), which can be controlled
with the graphical user interface, from the command line, using text files written in Gmsh's own
scripting language (.geo files), or through the C++, C, Python, Julia and Fortran application programming
interface.
GEOMETRY OPTIONS
-0 Output model, then exit.
-tol float
set geometrical tolerance.
MESH OPTIONS
-1, -2, -3
perform 1D, 2D or 3D mesh generation, then exit.
-o file
specify output file name.
-format string
