[Nek5000-users] implement pressure and velocity BC

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

Hi Neks,

I'd like to use some specific function to define boundary conditions for 
pressure and velocity in my simulation.

For example, I'd like to use for velocity Ux=Uy=0 dU/dz=a, and for 
pressure grad(p)=b. I've seen that in usercheck it is possible to write 
time dpendent functions to define the boundary conditions for velocity. 
But, is there any way to write Neumann boundary conditions for pressure 
or velocity? Or to write the function that I want?

Thank you in advance.
