I am trying to simulate closed-loop wind tunnel in 2D. I want to model the fan as "Fan boundary condition". According to Ansys documentation the Fan must be modeled must be modeled as the interface between cells http://www.afs.enea.it/project/neptu...ug/node254.htm.

AFAIK, in Design Modeler I can only create two surfaces, and specify the second surface as a Fan zone, then I have to change it to interior in Fluent (but in this case I have two interfaces).


Can you tell me how can I create the geometry with only one interface as illustrated in the image below?

Thank you
