User Controlled Mesh across two different geometries

Hello All,
I am new to COMSOL and would like to get some help with user controlled mesh. Attached is a figure I would like to model in COMSOL. The length is 2cm and the height is 1cm. When I try to use the user defined mesh. It meshes both bodies separately, so I'm unable to get the mesh which is in the figure.
Any help is appreciated.
Thank you
