Geometry ¶. This class provides a Python interface for the Gmsh scripting language. It aims at working around some of Gmsh’s inconveniences (e.g., having to manually assign an ID for every entity created) and providing access to Python’s features. In Gmsh, the user must manually provide a unique ID for every point, curve, volume created.

Yes, I do. It has alot more functionality than pygmsh (as pygmsh is simply a wrapper around the GMSH python API). You can of course mix the two of them, you can start creating your geometry with pygmsh, and then use the gmsh python API to fetch boundaries so you can mark them.
