Hi everyonev. I want to simulate a ball valve in Ansys Fluent without creating a physical barrier.
I'm interested in having flow when point A's temperature is above 90°, and stopping the flow (by defining certain conditions at point B) when the temperature is below 75°.
Does anybody know which type of UDF is relevant? And what should I define in order to receive the imaginary barrier at point B?
Thank you!
