Hi,
I am doing simple smooth pipe to get Nusselt number.
Defined periodic BC at fluent meshing side, and added 1e-3 uniform inflation.
When I switch to fluent, defined periodic bc and it worked. result was higher than dittus-boelter corelation
Then wantted to decrease inflation first layer to 3.1e-6 using y+ calculator.
But that time in fluent side periodic bc does not work and got below error.
What can be the reason?
Thank you,

That looks OK. You can always create a nonconformal periodic, that generally avoids problems.
I assume you checked the periodic energy equation fudge and how Fluent calculates Nu?

Define as "interface" & "interface_1" or "fred" & "ginger" but with the type as interface.

Nice to see the classic boundary name pairing. :)
It's running so the basics are OK. If you review the flowfield at around 20 iterations what is going on?

Check things like area values in Fluent alongside what the experimental values & errors are. I won't say the experiment is wrong, nor the CFD, but don't assume either is "correct" either.
