NAME

6       Gmsh  -  3D  finite element mesh generator with built-in CAD engine and
7       post-processor
8

SYNOPSIS

10       gmsh [file(s)] [option(s)]
11

DESCRIPTION

13       Gmsh is a 3D finite element mesh generator with a build-in  CAD  engine
14       and  post-processor.  Its  design  goal is to provide a fast, light and
15       user-friendly meshing tool with parametric input and  flexible  visual‐
16       ization capabilities.
17
18       Gmsh is built around four modules (geometry, mesh, solver and post-pro‐
19       cessing), which can be controlled with the  graphical  user  interface,
20       from the command line, using text files written in Gmsh's own scripting
21       language (.geo files), or through the C++, C, Python, Julia and Fortran
22       application programming interface.
