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

[edit]

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]
