[Nek5000-users] Pressure Normalization

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

Dear Neks;

I would like to know how the pressure normalization is done in the
code. Since I'm running a turbulent pipe flow with periodic B.C.s using
Pn_Pn-2 scheme, I would like to obtain P_rms values; however, the
pressure fluctuations does not look alright. I think in case of
inflow/outflow, the conditions are to set the pressure to be zero
at these boundaries; obviously this is not possible for periodic cases.

Many thanks;
Azad
