If rotor portion is rotating and you are explicitly resoling the rotor solid why not just creating an interface and using sliding mesh or rigid body motion. CHT and Solid Motion are always complex especially of the solid is not a surface of revolution. So you will have solid-rotor/fluid interface and fluid-casing interface. That will be my first try here if you can run transient.nWhich error message / warning are you getting?n
