Hello all and thank you for your help and support.
I am trying to do some analyisis on a room with air coming from the circle on top and coming out of the small slot on the lower side.
I started by sketching the room and then sketching the circle as an inlet and convert it to a face from sketch, but it is not working correctly in Mesh and analysis as it is not being able to define as an inlet.
How can I define this circle as a dependent face, I tried Boolean operation but it didn't work, I hope you understand what I mean, which is make this circle as an independent face and not related to the face that is drawn on.
Thank you a lot
