2d 1/2 axisymmetric annulus for POLYFLOW
 
When trying to import my meshed 2d annulus into polyflow, the axis of symmetry I want to use (meshed edge that runs along the r=0 line in cylindrical coordinates) is not attached to the face that represents half of the annulus. POLYFLOW does not want to recognize any boundary set (in this case, the meshed edge that I want to use as the axis of symmetry) that is not directly attached to the subdomain (in this case a single rectangular face representing half of the annulus). How can I successfully define the axis of symmetry for this simple case for use in POLYFLOW?

Was in contact with ANSYS as well....they told me that for POLYFLOW, the axis of symmetry should be defined along the Y-axis in Gambit...I don't think that was in any of the manuals. Also, according to the POLYFLOW manual, for axisymmetric models, POLYFLOW automatically applies r=0 as the axis of symmetry. So, I suppose there is no need to specify further as I was trying to do.

Maybe overlooking this: tell polyflow at the starting about axisymmetry

It's 10 years since, but for the future if anyone's needing help with this : Firstly make sure to select the axisymmetry option. 2. And it recognizes automatically, while imposing boundary conditions:
