Hello everyone,

I have shourdless tip rotor geometry along with housing as shown in the picture attached. I am having difficulty in modeling flowpath which accounts for all the details of the geometry.

If I create a flowpath as shown in the picture then I would be completly neglecting the shroud ring region . Does anyone has better idea in order to account for all the details in the flowpath?

P.S: I am looking at extracting single rotor flowpath and mesh it in turbogrid and later transform it into complete rotating region and assigning interfaces accordingly.

Any inputs would be helpful. Thanks!
