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: ************************************************** ***** Job Information Run mode: serial run Host computer: EROMU Job started: Sun Nov 3 17:10:47 2002 Details of error:- ---------------- Error detected by routine PSHDIR CDRNAM = /FLOW/PHYSICS/ZIF3 CRESLT = NONE ****** PROBLEM REPORT ****** Subsystem: Input Subroutine name: ErrAction Severity level: Fatal Error Error message number: 001100279 Message: Stopped in routine MEMERR An error has occurred in cfx5solve: The CFX-5 solver exited with return code 1.

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 < pre > ... < /pre > tag to designate pre-formatted text, then post the text. This will make the OUT file you just posted much more readable. Robin |

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. |
