[Nek5000-users] Periodic BC on non-parallel boundaries

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

Hi Stefan,

I tried the cyclic BC with Pn/Pn-2, but it didn't work. Visualizing the results, the velocities do not seem to be properly matched, and the fields quickly blow up. To make sure I was doing the cyclic BC right, I changed to no-slip and tried it with Pn/Pn, and that worked, so I think Paul may have been right about cyclic BC no working with Pn/Pn-2. Do you think there is a way around this? I unfortunately need the stress-free boundaries or something similar.

Best,

David
