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).
