[Nek5000-users] Transverse velocities with stress formulation

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

Hi Neks, hi Paul,

I have already asked the question about stress formulation and currently I
am testing stress formulation in pipe flow with variable viscosity. So I
have found strange thing: the longitudinal and transverse velocities at the
outlet are different with different pipe lengths(with same boundary
conditions at the inlet). Transverse velocities decrease and axial one
increase with pipe length increasing. That implies a kind of acceleration
in the pipe. Is there any explication for this? How transverse velocities
are calculated at the outlet?

Thanks in advance for any help,

Andrew
