Creating named sections
 

Hi,
I am simulating flow over an airfoil in ANSYS.
I have created my geometry and completed the meshing. All that is now left to do is created named sections (for inlet, airfoil, outlet etc) and then move on to FLUENT.
However, when I create these named sections, the 'airfoil' never becomes available to select in fluent when looking at boundary conditions - whilst inlet, outlet, upper and lower wall are viewable.
Has anybody else had this problem before and know the issue?
I created a 3D curve by importing coordinates for my airfoil.

Thanks
