Hi,all:
I implement a model as here http://www.cfd-online.com/Forums/ope...model-les.html

I want to output the model coefficient as it runs, the most simple way may be something like
Code:
Info<< "Uncorrected Ubar = " << magUbarStar.value() << tab
            << "pressure gradient = " << gradP.value() << endl;
as in channelfoam
However, when I tried like this, it seems that it doesn't work.
Can anyone point out whether it's possible?
I tried another method, by defining it as a scalarfield to output as the other variables such as U and p,but this requires an initial value, when I set the internal filed of it , the value keeps the same all the time, how can it be?

well, I find that if I define it as a scalarfield, it's almost the case of nuSgs which doesn't output as a field, just a file containing boundary conditions.

So is there any way to do this?

I find a much more easier way!

Defining cV as a volScalarField(don't do the volume average), so cV can be output as a field. Then we can calculate the volumeAverage of cV by using swak4Foam.

However, the question is:
Why the cV field is can output as a field? Here is the model

Here is the initial condition for cV
Code:
dimensions      [ 0 0 0 0 0 0 0 ];

internalField   uniform 0.07;

boundaryField
{
    in
    {
        type            calculated;
        value           uniform 0.07;
    }
    out
    {
        type            calculated;
        value           uniform 0.07;
    }
   
    hub
    {
        type            calculated;
        value           uniform 0.07;
    }

    shroud
    {
        type            calculated;
        value           uniform 0.07;
    }
    
    blade
    {
        type            calculated;
        value           uniform 0.07;
    }

    peri1
    {
        type            cyclic;
    }
    peri2
    {
        type            cyclic;
    }
}
I'm considering whether it's right to implement such kind of initial condition

The problem should be in the code that nuSgs is not output correctly, only the boundary values found. How do this come from? Can anyone help?
