Help,periodic boundary .WHO CAN HELP ME?

hello everyone:
i have a similar problem when reading a reference about porous meida.In order to be convinent for your reading and understanding the means.This paper was appended at the end of this text.
Now i descripe my question.This paper's auther make a periodic boundary conditions to simulation the effective thermal conductivity,in which he impose a temperature drop on the periodic boundary according to his cited reference [20].While when i see the cited reference 20,finding that,i need to modify the coefficient matrix of the discreted equations,yet this is just my guess.
Can you give me some suggestion on how to carry out this boundary using the fluent?
Any help will be appreciated!
Have a nice day ,my friend!;)
oh,sorry:( because the Max Filesize limit,i cannot upload the reference on to the forum.If you want to know more detail pleas load from this URL:

I have not good understand your problem! Your problem is how to set the periodic BC?

:)Thank you，felicemastronzo.As it was very busy in the last week, so
a quick reply was not sent to you.
Yes,my question is how to do the same work in the paper that i had mentioned using the comercial software Fluent?

In order to set the periodic bc you have to use the TUI of fluent. you have to type following

mesh (return)
mz (return)
mp (return)
and than the name of the bc

If you need more help, ask me without problems.
