Hi,

I need to find the flux through each cell of a boundary at each time step. As far as I know all fluxes through each cell are given in the phi file but how can I find them for a specific boundary patch?

I normally use the following function (which is placed in the controlDict file) to find the sum of the fluxes through all the cells in a boundary at each time step but now I want the actual value for each cell and not the sum. How can I do it?

functions
{
    inletFlux1
    {
        type            faceSource;
        functionObjectLibs ("libfieldFunctionObjects.so");
        outputControl   outputTime;
        log             true;
        valueOutput     false;
        source          patch;
        sourceName      inlet1;
        operation       sum;   // what should I write here to get value for each cell and not the sum?

        fields
        (
            rho phi alpha1
        );
    }
}

Thanks
