[Nek5000-users] specify direction of velocity inlet as boundary condition

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

Hi Ami,

'v  ' velocity specification means a direchlet BC when velocity 
ia prescribed by userbc()'s values ux,uy,uz cartesian components -- e.g.,

       ux = 1.
       uy = 0.
       uz = 0.

in userbc() of .usr will set velocity of 1 in positve x-direction.

Best.
Aleks
