dear all, i'd like to know, if it is possible to set the velocity inlet in an internal face in the flow, something like a pump. And in the same way, i'd lilke to set an outlet face that is inside the flow, like the flow disapeeared. Thanks all.

I would suggest you to write a UDF and access those face and add +ve (or) -ve source terms to them based on whether it is source or sink

U could make the face as sink
