Thanks for getting back.

What I was saying was in response to you saying, "To have 2 face zones on both sides of the circle, you can set a named selection on the face for each cell zone. Fluent should then recognize this."... then I said "you can see both named selections on the last pic above... "inner" and "outer" are both face zones for faces on both sides of the circle"... what I should have said was the named selections "inner" and "outer" represent the faces which I want Fluent to make zones out of (zones to be). Why Fluent doesnt make the zones with the named selections as is would be a good thing to know (perhaps easier to just changed the geometry / mesh settings?), and as you said Fluent should recognize the named selections and make the zones... but yes, I said they are both face zones in error... kingly ignore that...all else is accurate.

I did not create "wall-inner" and "wall-outer" myself and am not sure where to see them exactly... however, when clicking on areas and lines in the displayed mesh in Fluent a text box does comes up with similar wording which I think is equivalent (e.g. "wall-exterior")...

1) First pic "wall-exterior" are the upper and lower walls to the outer domain and both are highlighted but hard to see here (my understanding "walls" here are applied automatically by Fluent via symmetry... I did not have named selections of these lines...after inlet and outlet are assigned). 
2) In the second pic, "wall-interior" is the inner circle... how to I say this.. it is the ring... the red circle, not the face, which radius is slightly further out from the woud-be turbine radius... the only red circle. And of course this is the wall that the fluid is not entering during simulation.
3) Third pic shows the fluid cell zones... one exterior and one interior.
