Patches stator_outlet_* are of type mappedPatch to be connected to rotor region of the model. Patches stator_cyc_l and stator_cyc_r are of type cyclicAMI which interpolates variables between two patches. Patch stator_blade is of type mappedWall because heat transfer from fluid to solid is assumed. Patches stator_hub and stator_shroud are standard wall. Patch stator_inlet is standard patch, fluid can flow through.
