1.6 … and what Gmsh is not so good at

As of version 2.6, here are some known weaknesses of Gmsh:

• the BRep approach for describing geometries can become inconvenient/inefficient for large models. For complex models, or if you want to use a solid-modeler approach, you should link Gmsh with an external CAD kernel and import native files directly. (The binary versions available on http://geuz.org/gmsh/ are linked with the free CAD kernel OpenCASCADE, which enables native BREP import as well as STEP and IGES import.)
• Gmsh is not a multi-bloc generator: all meshes produced by Gmsh are conforming in the sense of finite element meshes;
• Gmsh’s user interface is only exposing a limited number of the available features, and many aspects of the interface could be enhanced (especially manipulators).
• Gmsh’s scripting language is fairly limited, providing only very crude loop controls and user-defined functions, with no local variables.
• there is no global “undo” capability. You will often need to edit a text file to correct mistakes.

If you have the skills and some free time, feel free to join the project: we gladly accept any code contributions (see section Information for developers) to remedy the aforementioned (and all other) shortcomings!
