[Nek5000-users] Boundary condition loop

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

Hi Josh,

Your approach is the only one I know of.

Note that there are many routines around that will access
the points that are on a given face pair (f,e), so you might
want to check the structure of those for your "Do computations"
block.

Don't forget "integer e,f"    :)

Cheers, Paul
