Hi all,

I'm new to fluent and have a basic problem that I need help with.

I have a square tube 50mm x 50mm x 200mm long. The tube is made of steel, open ended both sides. Generation in Gambit and meshing is ok.

I want to heat up the exterior of the bottom face to say 1000k and blow air through the tube at sy 3m/s. Heat will be conducted through the bottom face and radiate within the confinements of the tube.

I want to examine both the temperature on the other faces as well as the temp of the air flowing through the tube..........

I need help setting up the boundary conditions in Fluent....

Thansk....and be patient...I'm new to this.
