hello! i have some difficulty in computing rotor 37 with the k-epsilon(low Re yang-shih).i just use the same method to generate the mesh. it's successful to compute it by using the B-L,S-A.i feel a little bit confused.i want some guidence.thank you!

I think you should give the inlet K and epsilon value of rotor,which is very important.

for that u need to have very fine mesh as requeired by low renoldes number turbulence models
