CFD Online Discussion Forums - What does rhoEff mean in KinematicCloud.H?

Hi all,

What does rhoEff mean in KinematicCloud.H?

Code:

inline const Foam::tmp<Foam::volScalarField>

Foam::KinematicCloud<ParcelType>::rhoEff() const

{

tmp<volScalarField> trhoEff

(

new volScalarField

(

IOobject

(

this->name() + "RhoEff",

this->db().time().timeName(),

this->db(),

IOobject::NO_READ,

IOobject::NO_WRITE,

false

),

mesh_,

dimensionedScalar("zero", dimDensity, 0.0)

)

);



scalarField& rhoEff = trhoEff().internalField();

forAllConstIter(typename KinematicCloud<ParcelType>, *this, iter)

{

const ParcelType& p = iter();

const label cellI = p.cell();



rhoEff[cellI] += p.nParticle()*p.mass();

}



rhoEff /= mesh().V();



return trhoEff;

}

Does this mean the particles concentration per cell?
If it does, how do I output this parameter?
