Hi all,
I try to model a close loop inner flow. But I have no idea how to set B.C for the inlet and out. Any one ever try it before ?

Like Glenn said, we will need a little more information. Is there a pump moving the fluid around? buoyancy driven?

For the pump one, You can define a mass flow inlet, and set the temperature equal to the temperature at your outlet plus whatever heat the pump adds, then define an outlet at the pumps inlet.
Or you could use a momentum and energy source. But it really depends on what you are doing.
