Heat transfer between two fluids
 
Hello

I'm trying to model the heat transfer between two different fluids (H2Ovl and Air), and I used the following configuration interface:

DOMAIN INTERFACE: hot_cold
Boundary List1 = hot_cold Side January 1
Boundary List2 = hot_cold Side 1
Interface Type = Fluid Fluid
INTERFACE MODELS:
Option = General Connection
FRAME CHANGE:
Option = None
END
HEAT TRANSFER:
Conservative Interface Option = Flux
INTERFACE HEAT TRANSFER MODEL:
Material = Copper
Option = Thin Material
Thickness = 1 [mm]
END
END
MASS AND MOMENTUM:
Option = No Slip Wall
END
PITCH CHANGE:
Option = None
END
END
MESH CONNECTION:
Option = GGI
END
END

The problem I have is that the "cold fluid" warming fails. apparently exists heat transfer in one direction only, as the hot fluid (air).

I would appreciate your help.:)

Greetings.
