[Nek5000-users] periodic boundary conditions

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

Hi Neks,

related to the latter post. Is it possible to establish the connectivity 
between two faces in the usr file? I mean, if I set in the rea file

p 1 3 0 0 0 0 0
p 2 4 0 0 0 0 0

What should I write in the usr file to connect these two faces? Is it 
possible to do what I want?

Thanks in advance.
SL
