[Nek5000-users] Reynolds number setting in the turbChannel example

Dear Zhenrong,


Did you seed your initial conditions with any perturbation?


Did you fix your flow rate with p54/p55 in the .rea file?


Best,


Paul

Hello Neks

Thanks very much for all your kindly replys. And I am really sorry for not following this discussion in time because of the vacation. I will works on the example more deeply in the following days.
I still have a problem which might be very stupid, but I have no clue where the proleme is. I set p02 = -2800 and the grid domain is pi * [-1,1] * 2pi in z,y,x direction to reproduce the Re_tau = 180 case. But the simulation results is laminar! which is really strange.
And is there any existing post-code for calculate two points correlation and energy spectral?

Thanks again

Regards
