Propeller (Urgent Need Help!)
 

Hi, i am new with ansys fluent.. i have draw a propeller with a shaft.. my task is to do the simulation in order to obtain FFT graph.. but i have no clue on that.. Currently i was divide my propeller into two parts(propeller & shaft).. so may i know how should i set the cell zone condition and boundary condition?

i label my part like this:
(i) Cell Zone
- propeller = fluid
- shaft = fluid

(ii) Boundary condition
- interior propeller = interior
-interior shaft = interior
-propeller = wall (with rotation)
- shaft = axis

Is this correct?

Please help!!

Propeller without air outside?

how i model the air outside? do i have to build a tunnel for it?

Two Bodies: The air and the cylinder in which the propeller blades are cut. The cylinder rotates.
