Gmsh - 3D finite element mesh generator with built-in CAD engine
and post-processor
gmsh [file(s)] [option(s)]
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).
