Default 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:

************************************************** *****

BOUNDARY : io01 Interface A1

Boundary Type = INTERFACE

Location = io01 Interface A1

Coord Frame = Coord 0

BOUNDARY CONDITIONS :

MASS AND MOMENTUM :

Option = Conservative Interface Flux

END

TURBULENCE :

Option = Conservative Interface Flux

END

ADDITIONAL VARIABLE : h01

Option = Conservative Interface Flux

END

ADDITIONAL VARIABLE : h02

Option = Conservative Interface Flux

END

ADDITIONAL VARIABLE : h03

Option = Conservative Interface Flux

END

ADDITIONAL VARIABLE : h04

Option = Conservative Interface Flux

END

ADDITIONAL VARIABLE : h05

Option = Conservative Interface Flux

END

ADDITIONAL VARIABLE : h06

Option = Conservative Interface Flux

END

ADDITIONAL VARIABLE : h07

Option = Conservative Interface Flux

END

ADDITIONAL VARIABLE : h08

Option = Conservative Interface Flux

END

ADDITIONAL VARIABLE : h09

Option = Conservative Interface Flux

END

ADDITIONAL VARIABLE : h10

Option = Conservative Interface Flux

END

END

END

BOUNDARY : io01 Interface B1

Boundary Type = INTERFACE

Location = io01 Interface B1

Coord Frame = Coord 0

BOUNDARY CONDITIONS :

MASS AND MOMENTUM :

Option = Conservative Interface Flux

END

TURBULENCE :

Option = Conservative Interface Flux

END

ADDITIONAL VARIABLE : h01

Option = Conservative Interface Flux

END

ADDITIONAL VARIABLE : h02

Option = Conservative Interface Flux

END

ADDITIONAL VARIABLE : h03

Option = Conservative Interface Flux

END

ADDITIONAL VARIABLE : h04

Option = Conservative Interface Flux

END

ADDITIONAL VARIABLE : h05

Option = Conservative Interface Flux

END

ADDITIONAL VARIABLE : h06

Option = Conservative Interface Flux

END

ADDITIONAL VARIABLE : h07

Option = Conservative Interface Flux

END

ADDITIONAL VARIABLE : h08

Option = Conservative Interface Flux

END

ADDITIONAL VARIABLE : h09

Option = Conservative Interface Flux

END

ADDITIONAL VARIABLE : h10

Option = Conservative Interface Flux

END

END

END

************************************************** *****

I replaced it by:

************************************************** *****

BOUNDARY : io01 Interface A1

Boundary Type = INLET

Location = io01 Interface A1

Coord Frame = Coord 0

BOUNDARY CONDITIONS :

FLOW REGIME:

Option = Subsonic

END

MASS AND MOMENTUM:

Option = Normal Speed

Normal Speed = 3.18 [m s^-1]

END

ADDITIONAL VARIABLE: h01

Option = Value

Additional Variable Value = 1. [kg m^-3]

END

ADDITIONAL VARIABLE: h02

Option = Value

Additional Variable Value = 0. [kg m^-3]

END

ADDITIONAL VARIABLE: h03

Option = Value

Additional Variable Value = 0. [kg m^-3]

END

ADDITIONAL VARIABLE: h04

Option = Value

Additional Variable Value = 0. [kg m^-3]

END

ADDITIONAL VARIABLE: h05

Option = Value

Additional Variable Value = 0. [kg m^-3]

END

ADDITIONAL VARIABLE: h06

Option = Value

Additional Variable Value = 0. [kg m^-3]

END

ADDITIONAL VARIABLE: h07

Option = Value

Additional Variable Value = 0. [kg m^-3]

END

ADDITIONAL VARIABLE: h08

Option = Value

Additional Variable Value = 0. [kg m^-3]

END

ADDITIONAL VARIABLE: h09

Option = Value

Additional Variable Value = 0. [kg m^-3]

END

ADDITIONAL VARIABLE: h10

Option = Value

Additional Variable Value = 0. [kg m^-3]

END

END

END

BOUNDARY : io01 Interface B1

Boundary Type = OUTLET

Location = io01 Interface B1

Coord Frame = Coord 0

BOUNDARY CONDITIONS :

FLOW REGIME:

Option = Subsonic

END

MASS AND MOMENTUM:

Option = Static Pressure

Relative Pressure = 1. [bar]

END

END

END

************************************************** *****

And deleted this from the end of the ccl file:

************************************************** *****

DOMAIN INTERFACE : io01

Interface Type = Periodic

Boundary List1 = io01 Interface A1

Boundary List2 = io01 Interface B1 END

************************************************** *****

The solver stops with the following error message:

************************************************** *****

What would be the problem?

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.

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.
