Conformal Mesh for MRF
 

Hi,
I am trying to generate a conformal mesh for a MRF simulation on Fluent, but the only way I have read up to now is that I have to enable "Shared Topology" in the part (Ansys DesignModeler). The issue that this causes it that I can't now define the shared but different surfaces that make contact, which are the stationary and rotating cylinder (Outer and inner interface), without these the Fluent won't accept the mesh.
Is there any other way to gain a conformal mesh without sharing topology.
