[Nek5000-users] Pipe flow and pressure normalization

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

Dear Neks,

I am running a turbulent pipe flow simulation with periodic boundary  
conditions.
At this point, the pressure normalization is set such that the spatial
average of p is zero at each time-step. This is totally fine. However,  
I would like to change the normalization such that the spatial average  
of p on the wall is zero at each time step, i.e. in order to get the  
average pressure <P> = 0 on the wall.

Could I get some guidance on where/how to change the normalization in  
the code.
The way the pressure is normalized affects the prms values obtained  
from the run. This is in addition to other statistical quantities such  
as the skewness and flatness of p.

Best regards
George
