velocity gradient at outlet boundary
 
hi, i want to make a velocity gradient at outlet boundary,i don't know if i have to use velocity inlet boundary and how i make that?

I don't think it would be possible to define outlet gradient. You can just define zero gradient using outflow boundary condition.

i think i've tried that, by making the outlet as velocity inlet, and define the value of the cells in the boundary.but i don't know if it works, it's calculating now.
