Neumann BC at the outlet in laminar flow module

I'm trying to solve a microfluidic flow problem where inlet BC is velocity (dirichlet BC) and outlet BC is velo flux (neumann BC). In the laminar flow module, i do not get option for neumann BC @ outlet.
Comsol manual states that velocity @ inlet and outlet is not feasible. It has to be velo and pr or vice-versa.
The solution converges fine with velo @ inlet and pr BC @ outlet but the axial pr gradient does not match solution in literature.
Any help/advise is appreciated.
