NAME

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

SYNOPSIS

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

DESCRIPTION

13       Gmsh is a 3D finite element grid 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  advanced  visual‐
16       ization capabilities.
17
18       Gmsh is built around four modules: geometry, mesh, solver and post-pro‐
19       cessing. The specification of any input to these modules is done either
20       interactively  using  the graphical user interface, in ASCII text files
21       using Gmsh's own scripting language (.geo files), or using the C++,  C,
22       Python or Julia Application Programming Interface (API).
