[Nek5000-users] Set gradient and/or pressure at outlet

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

Thanks Paul for the answer. Yes, I'm using Boussinesq approximation, but
using incompresible equations, there are no stratification in the density,
like the equations you mention. But, anyway, I'm more interested in setting
the spatial gradient equal to cero in the boundary. ¿How can I achieve that?

dUy/dy=0

dTEMP/dy=0


Thanks a lot,
Juan Pablo.
