[Nek5000-users] Pn-pn formulation

[nek5000-users at lists.mcs.anl.gov]

Hi Neks,

I found that in the turbulence channel example, (Pn-Pn) formulation is 
used instead of (Pn-Pn-2) is there a reason behind to choose that 
formulation for the channel flow (SEM) ??. Could some one please tell me 
what difference does it make.

Thanks in advance

Best Regards,
