Hi:

It looks like the velocities are where the interface goes from radial to axial.  I would suggest splitting this interface into three connections and making named selections for the pairs. This will help the frame change numerics.

Leave the mesh non-confomal at the interface, ie: no share topology. Import the mesh and then create A2, A2 and R1 - three interfaces to connect axial-radial-axial.  You can create these interfaces in the regular interface creation tool as shown below:
