Some questions

[mohsamaz]

Hello everyone,
I am new with working CCBlade.
I appologize for asking question here.
because I dont know where is discussion forum of WISDEM/CCBlade.

anyway, I am using wisdem. and I have some questons.
in example 10_ccblade(https://wisdem.readthedocs.io/en/master/examples/10_ccblade/tutorial.html#) , r shows the center point of each section? or start of each section?
r = np.array(
[
2.8667,
5.6000,
8.3333,
11.7500,
15.8500,
19.9500,
24.0500,
28.1500,
32.2500,
36.3500,
40.4500,
44.5500,
48.6500,
52.7500,
56.1667,
58.9000,
61.6333,
]
is there any geometry picture that shows what is exactly Rhub, Rtip,r?

another question is
why "Cylinder" repeated in af_names?
af_names = ["Cylinder", "Cylinder", "DU40_A17", "DU35_A17", "DU30_A17", "DU25_A17", "DU21_A17", "NACA64_A17"]

af_idx = [0, 0, 1, 2, 3, 3, 4, 5, 5, 6, 6, 7, 7, 7, 7, 7, 7]

if we can in af_idx by 0 show 3 times Cylinder section that has been used, but in yaml file in airfoils section there is just one Cylinder? why "Cylinder" repeated?
Best regards,

More details on the BEM method implemented in CCBlade in WISDEM can be found here. The airfoil names correspond to the the airfoil geometry and polars used at the radial stations you copied (the r-vector).
