Hello everyone.

I am trying to simulate a rotor in hovering mode in fluent. And I wanted to use the Source-sink boundary condition in the farfields. Can anyone give me a few guidelines on how to write a UDF to use this BC in Fluent?

A little about the Source-sink boundary condition is that a point sink pulls the flow towards the center of rotation from the surrounding into the computational domain resulting in a velocity given by Wi𝑛=−√𝐶𝑡/8*(R/d)^2. And flow exits the domain through an exit plan on the lower boundary.
Please see the attached image for details.

Thank you.
