need help - mixed convection in vertical duct
 

Hello,

I want to simulate a coupled problem like mixed convection (combination of free and forced convection) in a vertical duct.In the two user guides available in website I can only find simple problems like lid driven cavity, dam break etc. but couldn't find any coupled solver. Can anyone give me instructions on how to start a problem like this, are there any other user guides available.

Thank you
