How can I set different temperatures in a volume?
 

Hi, everybody:

I'm new in Fluent simulation.

In my recent simulation case, I set the inlet temperature and the outlet temperature on a pipe.

Can I set different temperatures on a pipe? How can I do it?

The attachment is the picture shown my case, the red words are what I would like to set.

Please give me some tips, thanks.

I'll assume you meant you have two halves of your domain which you'd like to initialise at different temperatures: an upstream and a downstream section. You could either patch the domain with the temperature values (have a read of "Patching Values in Selected Cells" in the users guide) or employ a user-defined function (have a read of the DEFINE_INIT macro in the UDF manual).
