About Gmsh
Gmsh generates finite element meshes for simulation work. It is built around four modules: geometry, mesh, solver and post-processing. It can be driven from a graphical interface, the command line, .geo script files in its own language, or APIs for C++, C, Python, Julia and Fortran.
Builds are available for Windows, Linux and macOS on x86 and ARM, with a related ONELAB app on Android. A reference manual and tutorial are provided. It suits engineers and researchers preparing geometry and meshes for numerical solvers.
Strengths
- Geometry, meshing, solver and post-processing in one tool
- Scriptable through .geo files and several language APIs
- Runs on Windows, Linux and macOS including ARM
- Thorough reference manual and tutorial
Limitations
- Specialist tool that assumes finite element knowledge
- Interface is functional rather than polished
