[Nek5000-users] ON boundary condition

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

Hi Adam,

I set up ON bc some years back to support Blasius boundary layer
analysis in which the tangential (streamwise) velocity is
prescribed and the wall-normal velocity is allowed to escape
as the velocity boundary layer thickens.  This also implies
that the pressure is fixed on the upper surface.   This feature 
was developed  for Pn-Pn-2 and hasn't been extensively tested
in many years.   If this is a feature that you need, we could
look into resurrecting it.  (Note that the "escaping" feature
implies that the surface is aligned with either x,y, or z, and
not inclined w.r.t. these principal axes.)

Cheers,

Paul
