cyclic boundary conditions for airfoil

i am trying to do some cyclic calculation for an foil of an helicopter and want to use cyclic boundaries.
the plan is, to the outlet after the foil for the inlet in front of the foil. but how can i realise that?
i changed the boundary files as follows:
i attached a picture of the mesh.

You would need to either apply a body force in the solver, or maybe (I have not used it), use one of the jumpCyclic boundary conditions. This should allow you to have a jump in the pressure across the cyclic boundary, which will drive the current.
With respect to adding a body force in the solver, you will be able to find discussions on this forum.

Can you introduce me any thread about adding body force to solver in order to use cyclic boundary condition?
I've read and ran channel foam tutorial but I can't use cyclic boundary condition for my solver.
My case in a pipe which I want simulate one cross section of that in a fully developed state.
TanX very much
