Periodic Rotational Boundaries with Pressure increase

Dr. Flow Squad · February 19, 2020, 10:08

I want to model a Periodic case where I only focus on half of the flow and utilized Rotational Boundaries from below to top. se picture. I want to set up a periodic boundary where I can vary the Pressure increase dp, so I am able to get the same velocities but with an increase in pressure. How is that done?

As far as I know, ANSYS CFX does not support pressure drop across rotational periodic interfaces.

I can only see, translational periodic interfaces with Pressure Change.
