Physx 3.3.2 fluid simulation -- Parabolic velocity distribution

In PHysx 3.3.2, can the velocity of fluid in vessel distribute as parabolic velocity distribution, that is maximum in the center of the vessel, and minimum close to the wall? Because I found that in my experiment of fulid simualtion using Physx 3.3.2, the fluid velocity distribution is constant along the radius of the vessel.
Thank you
