Hexpress marine propeller mesh for one blade can be arrayed polar?
 

Hello,

Is there any chance I can repeat by a polar array a meshed domain blade?
Fine/Marine's Monitor displays slightly different thrust and torque for each individual blade because of mesh differences.

I've attached the closed solid domain for only one blade in STEP format.
Using polar array, for 5 items, would generate a cylinder with the propeller inside, subtracted.

At very low advance speeds, thrust and torque imbalance is quite large.
I'm trying to get an efficiency curve...

Thank you!

Propeller the Estimation of performance challenges( regarding mesh )
 

Hello.
I entered CFD of the freshman.
This difference was not me introduce the propeller thrust and we estimate the torque using the (STAR-CCM+).
But, advance ratio rises, with an error, causing heavy.
That's probably the problem of <arrangement of mesh>
Which mesh upstream and in downstream they focused on should I ?
I want to have the know-how of you guys.

Fluid region = 80M
Prop region = 320M

How do I approach?
