[Nek5000-users] Curved boundary

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

Thank you, Stefan!

The tarball v17.0 has version 17.0.4, so I suppose the 17.0.0 version I 
have was downloaded from github before the current v17.0 tarball 
(17.0.4) was available.

As long as it seems to work for my application, I think I'll just keep 
the test disabled. If you want to consider enabling this feature again 
at a later time, I can give details about my case. (It is simply flow 
between two cylinders, where the inner is solid and the outer is SYM. We 
want the pressure field at the inner surface, thus the PN/PN.)

Anyway, yes even in v17.0 we disabled certain features for PnPn as some combinations are not yet supported or well tested. It's very likely that some of the might work out of the box but we offically we don't support them (at least for now).
