This is not a surface mesh generator bug:
- the solve bloc do not use any domain. It is "solve(u) in M" and should contain "solve(u) in Omega by M".
- The problem here is a wrong error message. It should say: "cannot use POVRef boundary in standard FEM discretization. Specify a domain to do so: 'solve (u) in Omega by Mesh'" or so.
