CFD Online Discussion Forums - How to specify mixingPlane averaging scheme for a field

Hello.

For a mixing plane in my actual casre, I would like to set each averaging scheme separately.
So I commented out the default option and try to set each point separately.
However, I have problems setting the scheme for rho*U.

Starting from the error message:

Code:

--> FOAM FATAL IO ERROR:

Cannot find mixing type for field (rho*U)

Please specify in fvSchemes in mixingPlane, under field name

Available types are

6

(

fluxAveraging

uniformValue

unknown

uniformGradient

zeroGradient

areaAveraging

)

Accordingly in fvSchemes i've tried the following notations specifying the field rhoU, but nothing of these worked:

Code:

rho*U              fluxAveraging;

rhoU               fluxAveraging;

(rho,U)            fluxAveraging;

field(rho*U)       fluxAveraging;

field(rhoU)        fluxAveraging;

field(rho,U)       fluxAveraging;

For other Values it looks like:

Code:

mixingPlane

{

    //default  unknown;

    p         areaAveraging;

    U         fluxAveraging;

    rho       fluxAveraging;

    T        fluxAveraging;

    k        fluxAveraging;

    episilon fluxAveraging;

 }

Has anyone an idea how to specify the field rho*U in this context?
