san.pirate is on a distinguished road

How do we specify the Neumann boundary conditions or Zero streamwise gradient at the outlet in a pipe in CFX-pre. There are options only for Static Pressure, Avg. Static Pressure, Velocity components, Mass flow rate and Normal speed.
I need to specify derivative of all the variables to zero, I couldn't find clear help from ANSYS.

I am wondering whether I need to specify any additional variable? If so, how is that done.
