Gmsh is a finite-element mesh generator developed by Christophe Geuzaine and Jean-François Remacle. Released under the GNU General Public License, Gmsh is free software.

Gmsh contains 4 modules: for geometry description, meshing, solving and post-processing. Gmsh supports parametric input and has advanced visualization mechanisms. Since version 3.0, Gmsh supports full constructive solid geometry features, based on Open Cascade Technology.^{[1] [2]}

A modified version of Gmsh is integrated with SwiftComp, a general-purpose multiscale modeling software. The modified version, called Gmsh4SC, is compiled and deployed on the Composites Design and Manufacturing HUB (cdmHUB).

Interfaces

Various graphical user interfaces exist that integrate Gmsh into their workflow:

• A Matlab interface available with FEATool Multiphysics.
• The Mesh and FEM Workbenches of FreeCAD support Gmsh for meshing inside the program, along with other meshers like Netgen.^{[3] [4]}
