Hello,

I am trying to do a geometry for a 3D turbine blade with its fluid domain around it. I want to use rotational periodic boundary condition. I know how to do it if the geometry is like "a cake slice" with the blade in it. but I want the periodic boundaries to be with the same shape of the blade edges not straight surfaces like the cake slice. I am attaching a pic to show the desired periodic boundaries. How to do it rotational periodic boundary condition? I am using design modeler, Ansys meshing "workbench" and Fluent.
Thanks a lot.
