[Nek5000-users] problem with closed internal boundaries

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

Hello Michael,

I am by no means knowledgeable concerning NEK, but will put my two-cents
in by saying that I believe that all dimensions in the z-direction must
be 1.  However, you have "parameter (lz2=lz1-2)" and "parameter
(lz3=lz2)".

Cheers,
Frank
