Emanuele,
Well first you need to make 2 line loops, one for the airfoil and one for the farfield(in userguide) Then make a plane surface using the 2 loops.(userguide) You will then be able to mesh To control the mesh size use the characteristic length(userguide) If you want to then want to use a boundary layer you will be stuck the same place as I. It is easy enough to create a boundary layer with the extrude function, but I have yet to figure out how to attach it to a farfield mesh.
