Chilli83 New Member Michael Join Date: Apr 2009 Posts: 20 Rep Power: 17	Hi all I have to model a permeable surface upon an inlet boundary. From the surface I also need to specify a heat flux. The problem I have tried to illustrate on the figure at the link: The way I have tried to handle it is to define the geometry of the room and define the inlet and outlet by the “Imprint Faces” command. Then I define the surface as a solid which I use the “Frozen” command and then I put the room into an enclosure so I have one part consisting of two bodies. But when I go to the pre in CFX I can not find out how to define it as a permeable surface without a thickness. How can this be done? Kind regards Michael
