Replace periodic by inlet-outlet pair
 
Hello!

I performed a calculation defined with 25 pieces of periodic interfaces. I would like to solve mixing, so I have 10 additional variables. I turned off the additionals by ccl editor (solve scalar = f) and solved the flow. Than I wanted to set additionals as inlet parameters. So I turned on the additionals (solve scalar = t) and off the flow (solve fluids, solve tke omega = f) in the res file. And than changed one of the periodic pairs by inlet and outlet. The original ccl is under:

I replaced it by:

And deleted this from the end of the ccl file:

The solver stops with the following error message:

Have you spoken to your CFX support team?

Hi Lego,

Here's a little HTML tip. If you want to post a file exactly as it appears, use the &lt pre &gt ... &lt /pre &gt tag to designate pre-formatted text, then post the text. This will make the OUT file you just posted much more readable.

Re: Replace periodic by inlet-outlet pair
 
Lego,

You definitely cannot make this change directly in the CCL because changes on domain interfaces have ramifcations for the mesh and topology which can only be modified using CFX-Build.

The only way to get this working is to delete the domain interface in CFX-Build and rewrite the grid to a new defintion file. You should then be able to use the interpolater to copy your old solution over.

Neale.
