Duct inlet suction modeling

DrDerpy13 · June 12, 2021, 12:40

Hello guys,

I have a duct and an air volume and what i am trying to simulate is the air flow from the air volume into the duct. By this i mean, i want to see how air comes into the duct. The problem that i encounter is that ansys always creates an interface between the duct and the air volume, and as far as i know, one can't attribute any boundary condition to an interface like inlet or outlet. Any idea will be helpful, many thanks!

You don’t need an interface between your duct inlet and the air volume.
Your inlet/s and/or walls should be on the surfaces around your air volume.
Specify which are walls and which are inlets.
Your air volume mesh needs refining; it’s way too coarse
