Hi All,

I have setup a simulation with a good set of measures... For this task I am using swak4Foam. The simulation seems to be OK, although I still need to check for coherence of the values. However, something that is baffling me is the good amount of warning messages that are coming out:

 Expression UMeanAtPlane01LeftBranch : --> FOAM Warning : 
    From function ExpressionResult::getUniformInternal(const label size,bool noWarn)
    in file ExpressionResult/ExpressionResultI.H at line 324
    The minimum value 0.00897812 and the maximum 5.5276 differ. I will use the average 0.409302
 sum=0.409302 average=0.000113822
Expression pAvgAtPlane01LeftBranch : --> FOAM Warning : 
    From function ExpressionResult::getUniformInternal(const label size,bool noWarn)
    in file ExpressionResult/ExpressionResultI.H at line 324
    The minimum value -2.21591e-05 and the maximum 9.08284e-06 differ. I will use the average 1.37541e-07
 sum=0.000494599 average=1.37541e-07
Expression rhoFlowAtPlane01LeftBranch : --> FOAM Warning : 
    From function ExpressionResult::getUniformInternal(const label size,bool noWarn)
    in file ExpressionResult/ExpressionResultI.H at line 324
    The minimum value 0.00897812 and the maximum 5.5276 differ. I will use the average 0.409302
 sum=3.04379 average=0.000846439

What does exactly this mean? Should I correct something within the swakExpressions? Here I am attaching those too (in case a big guru wants to jump in... )

    createPlane01Parent
    {
        type            createSampledSurface;
        outputControl   timeStep;
        outputInterval  10;
        surfaceName     plane01Parent;
        surface
        {

            pointAndNormalDict

                normalVector    (0.00000  -1.00000   0.00000);
            };
            interpolate     true;
        };
    }

    UMeanAtPlane01Parent
    {
        type            swakExpression;

        expression      "UmeanPlane01P0*area()/sum(area())"; //
        accumulations   (sum average);
    };
    
    pAvgAtPlane01Parent
    {

        valueType       surface;
        surfaceName     plane01Parent;
        verbose         true;   
        variables       "pAvg{internalField}=p*vol()/sum(vol());";
        expression      "pAvg";
        accumulations   (sum average);
    };

    rhoFlowAtPlane01Parent
    {
        globalScopes    ("thisSimulation");
        // Function generated to get average of rho in a Plane.
        type            swakExpression;
        valueType       surface;
        surfaceName     plane01Parent;
        verbose         true;
        variables       "UmeanPlane01P0{internalField}=mag(U);";//*area()/sum(area());";
        expression      "rhoDensity*UmeanPlane01P0*area()";
        accumulations   (sum average);
    }

and another set of expressions are given by:

    createPlane01LeftBranch
    {

        outputControl   timeStep;

        surface

            type            cuttingPlane;
            planeType       pointAndNormal;
            pointAndNormalDict
            {
                basePoint       (-1.6000  -2.771281  0.00000);
                normalVector    (-0.5000  -0.8660254 0.00000);
            };
            interpolate     true;
        };
    }

    UMeanAtPlane01LeftBranch
    {
        type            swakExpression;
        valueType       surface;
        surfaceName     plane01LeftBranch;
        verbose         true;   
        variables       "UmeanPlane01{cellZone'leftBranch}=mag(U);";//*area()/sum(area());";
        expression      "UmeanPlane01*area()/sum(area())"; //
        accumulations   (sum average);
    };
    
    pAvgAtPlane01LeftBranch
    {
        type            swakExpression;
        valueType       surface;
        surfaceName     plane01LeftBranch;
        verbose         true;   
        variables       "pAvg{cellZone'leftBranch}=p*vol()/sum(vol());";
        expression      "pAvg";
        accumulations   (sum average);
    };

    rhoFlowAtPlane01LeftBranch
    {
        globalScopes    ("thisSimulation");
        // Function generated to get average of rho in a Plane.
        type            swakExpression;
        valueType       surface;
        surfaceName     plane01LeftBranch;
        verbose         true;
        variables       "UmeanPlane01{cellZone'leftBranch}=mag(U);";//*area()/sum(area());";
        expression      "rhoDensity*UmeanPlane01*area()";
        accumulations   (sum average);
    }

Any help or hint is greatly appreciated!!!
