Patches rotor_inlet_* are of type mappedPatch to be connected to stator region of the model. Patches rotor_cyc_l and rotor_cyc_r are of type cyclicAMI which interpolates variables between two patches. Patch rotor_blade is of type mappedWall because heat transfer from fluid to solid is assumed. Patches rotor_hub and rotor_shroud are standard wall. Patch rotor_outlet is standard patch, fluid can flow through.
