[Nek5000-users] Recycling BC

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

Dear Neks,


I am using the turbJet example to set up my own recycling boundary case.


As far as I understand the velocity that is passing through stack 8 (element 8) in the turbJet example should then be recycled back to the inlet.


However when I plot the instantaneous velocity profiles for these two points they are non-identical. Is this deliberately so, I presume it should behave like a periodic boundary condition, or have I missed the point?


Thank you for your time, Friedrich.
