[Nek5000-users] ffx ffy ffz from current run

Dear Zhai,


I've also tested the procedure and did not have any difficulty.


What, exactly, is your target Reynolds number?


When you were running the fixed flow-rate case, what were

the settings for ffx,ffy,ffz in your usr file?


Best,


Paul

Dear Paul,

After last request email (https://lists.mcs.anl.gov/mailman/htdig/nek5000-users/2018-March/005178.html), the ffz value of 0.01525 was obtained by 'grep volf logfile'. Then I used this value as ffz in usr file with changing para54 and 55 as 0 in the same time. The case was started from previous stop which is based on keeping flowrate.

After long time running (delt t*=200), the streamwise velocity was decreased compared with previous running . May I know what I can do to get the turbulence and velocity back?

Kind regards,

Zhai
