Hello everyone,

I have been studying on rayleigh step bearing for a while. Most of the approaches to solve the problem includes Reynolds' Equation. What I want to do is solving the same problem with full NSE. Regarding the nature of the problem, I need to have a fully developed flow at inlet while having zero statik pressure at the inlet. In this way, I expect to see a pressure distribution starting from zero to max value at step and then decrease to the zero until the outlet.
In literature, I have seen different approach both Reynolds' eq and NSE, and they were able to obtain this distribution. However, as far as I know it is not possible to force the inlet with both pressure and velocity input.
Is there any way that I can obtain this kind of distribution on ANSYS Fluent?

The work principal relays on zero-gauge pressure inlet and outlet (p1=p2) and all the flow movement are caused by moving wall on bottom. Top is no-slip stationary wall.

thank you,
