Gmsh is an automatic three-dimensional finite element mesh generator with built-in pre- and post-processing facilities.
With Gmsh you can create or import 1D, 2D and 3D geometrical models, mesh them, launch external finite element solvers and visualize solutions. Gmsh can be used either as a stand-alone program (graphical or not) or as a library to integrate in C++, C, Python, Julia or Fortran codes.
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. The specification of any input to these modules is done either interactively using the graphical user interface or in ASCII text files using Gmsh’s own scripting language.
This is free and open source software.
Key Features
- Based around four modules: Geometry, Mesh, Solver and Post-processing:
- Gmsh can be used at 3 levels:
- Through the GUI
- Through the dedicated .geo language
- Through the C++, C, Python and Julia API
- Main characteristics:
- All algorithms are written in terms of abstract model entities, using a
Boundary REPresentation (BREP) approach. - Gmsh never translates from one CAD format to another; it directly accesses
each CAD kernel API (OpenCASCADE, Built-in, …
- All algorithms are written in terms of abstract model entities, using a
