Cylinder placed in atmosphere

Hello,
I am a new user and I had a problem solving one of the multiphase dispersion problems in Workbench. I have a cylinder with a hole (leak) on one end which is placed in an atmospheric enclosure. The cylinder is carrying supercritical CO2. I want to study the dispersion of supercritical CO2 from that leak into the atmosphere. I created a solid pipe first and then extruded (cut) a smaller cylinder on one end through this pipe (which represents the leak) and placed it in a rectangular box which was created by extruding and selecting frozen retaining both the geometries. Then I created a Boolean and subtracted those two entities. After creating named selections and meshing the surface, I am trying to set up the model in Fluent. I want to give 2 inlets here- one for the inlet atmosphere and one for inlet through the pipe. But Fluent sets the default BC of the pipe inlet to 'interface'. I wanted some help on how the geometry for this kind of a problem should be created so that I can give two fluid BCs-one for air and the other for pipe. Thank you in advance.
