Dear Experts
I need help and guidance from you. Need to do simulation in CFX. I have a coil
and hot air is entering in that coil at 750 K with inlet velocity of 0.2 m/sec and exiting into the atmosphere. That coil is enclosed inside a drum filled with water at 298.15 K, and water is closed inside the cylinder. Need to simulate the heat transfer from coil to water.
It may be a simple problem for you all but for me its difficult.

What i have done so far in CFX.
I made two domains in CFX, one is air and other is water. As both the fluid are separated and not touching each other i am not using homogeneous.
What is the mistake i am making ....... plz help

CCL file is attached
