Meshing along a curve in 2D in fenicsx

General
1

I first define a square.

dish = gmsh.model.occ.addRectangle(0, 0, 0, L, W, tag=1)

arc = gmsh.model.occ.addCircle(0, 0, 0, r, tag=2)

How can I create a mesh along the circle that also mesh the arc of the circle?

It is unclear to me what you want to do. A sketch would be beneficial.
Do you want to mesh a square where a circle is embedded? If so you should use gmsh Boolean fragments, as shown in

Please note that your example is incomplete, missing essential imports to make it reproducible. Please note that at the moment it is also a pure gmsh question.

As recently done for all other pure gmsh questions, I am going to close this and ask that you post your question at Issues · gmsh / gmsh · GitLab, i.e. gmsh support channel.
