Default Gmsh: Structured Mesh problems

I am trying to get a 2-D structured mesh in gmsh with the transfinite algorithm. The domain is square, but in order to implement a variety of boundary conditions, I have broken up the lower boundary into 3 segments. When I try to recombine the mesh to get a structured mesh, I get an error saying "Surface is transfinite but has 6 corners". Is there a way to get around this problem? I want my domain to look like the bottom boundary is just 1 line, but be able to apply different boundary conditions in different sections of the bottom boundary.

Thanks for your help!

You bascially want to create a Transfinite Surface with 6 sides, right? if I understand your question correctly, it would be possible to divide your whole domain in three parts. Apart from that, I guess there is no way around it using gmsh.
Of course you can try to patch your domain afterwards with OpenFOAM or other utilities.

Best regards,
