I'm trying to compare the stall behaviours or an aerofoil in standard planar configuration and Axisymmetric configuration to see if the stall point changes significantly. I am trying to design a difuser for a wind turbine for my bachelor thesis.

The probem is, whist I have had no problem reporting the lift force created by an aerofoil in standard 2D configuration, in axisymmetric setup the Y component of force just reports as zero. This is not physical. Unless of course it is reporting the net force for the whole diffuser ring.

Whilst I do understand the conundrem that in axysymetric configuration the 'lift' force is radial and not strictly in the cartesian Y direction, it is in the Y direction according the slither modeled by the mesh so I expect it should be possible to report lift. But I cannot find any other way to report forces from an axysymetric simulation.

Is there any way I can report force in the radial direction? I can understand it may be be in N/rad or somesuch unit
