Hello. Can you help me in the open channel? problem is that you see on the picture below the channel has an input and output. geometry there is no problem. The water temperature of 3 degrees at the entrance channel and the ambient air temperature and the temperature of the channel walls of the exit channel is how many degrees? Does freezing Do not want to see it. There is a certain rate of water etc. could not make; fluent in CFX or open channel flow boundary condition that there is a how we will show you how to do please help. or Is there a tutorial or an example like that in your hand. Thank you all in advance. Regards.

hi,
it seems that there's a tutorial using free surface model in CFX help. btw, you need another mesh of ambient air |

you should mesh an air mesh big enough that the temperature and flow will not influence its outer boundary condition any more.
as to the free surface model, you can refer to the tutorial |
