Initialization of a turbo component requires the following:
Input for calculating a background mesh. For details, see Purpose of Background Mesh.
Specification of the number of instances of each turbo component (such as stator, rotor, and so on) required to represent the full geometry around the rotation axis.
Note: CFD-Post can initialize turbo space only for domains that are enclosed with inlet, outlet, hub, and shroud regions. For more complex geometries, you must set up the problem to isolate the region of interest into a separate domain that has these regions.
