Periodic BC in Fluent

nvarma · February 7, 2018, 15:11

Hey all,
I am trying to set up a transnational periodic BC. However, unlike shown in the manual, the created boundary only has "translational/periodic" option.

i,.e the massflow rate options are not visible.

The problem is one with a pressure gradient. And the inlet and outlets we set so before creation of the periodic boundary.

Can anyone point out what I am missing?

Did you do this to make the periodic boundary pair?

Code:

/define/boundary-conditions/modify-zones make-periodic

@LuckyTran No I used

Quote:

mesh/modify-zones/make-periodic

My problem is that the newly created periodic boundary doesn't have any input fields, just a selection between "translational" and "rotational"

Let me try what you suggested. Didn't know there was a TUI like that.

Thanks.

Okay figured.

In the newer versions, a new button enables called the "periodic conditions" next to the operating conditions. The parameters are entered there.
