Hi,
Before, I had used lcsMassFraction(cloudName) from swak4Foam function objects to convert lagrangian particle concentration into eulerian mass fraction. This was how I did that and it worked perfectly:

    mu
    {
        type expressionField;
        expression "18.6";
    dimension [1 -1 -1 0 0 0 0];
        fieldName mu;
        autowrite true;
    }

    rho
    {
        type expressionField;
        expression "1.25";
    dimension [1 -3 0 0 0 0 0];
        fieldName rho;
        autowrite true;
    }

    particles
    {
        type evolveKinematicCloud;
        cloudName particleCloud;
        g "down" [0 1 -2 0 0 0 0] (0 -9.81 0 );
        rhoName rho;
        muName mu;
        UName U;
    }

    massFractionKinematic
    {
        type expressionField;
        autowrite true;
        expression "lcsMassFraction(particleCloud)";
        outputControl timeStep;
        outputInterval 1;
        fieldName massFraction;
    }

However when I try to use it in solver icoUncoupledKinematicParcelFoam, like this:

massFractionKinematic
    {
        type expressionField;
        autowrite true;
        expression "lcsMassFraction(kinematicCloud)";
        outputControl timeStep;
        outputInterval 1;
        fieldName massFraction;
    }

I get the following error:
