Dear all,

I am trying to simulate airflow distribution in a room that is ventilated through a series of ducts. I have produced the fluid cavity of the room (fluid) and the body of the duct (fluid) with the wall surfaces of the duct labelled as wall BC using named selection. The respective BC such as inlet, outlet and Interior (Diffuser) were also labelled properly.

However, after producing the mesh, after initialising the setup, the diffuser surfaces set as interior BC showed up as both Interior and wall BC.

Could anyone suggest what i should do to correct this issue as i could not manually set the diffuser (wall BC) into an interior BC? There were also a bunch of wall BC that doesn't display anything when i click on display.
