Dear all,

I am now using icoUncoupledKinematicParcelFoam in Openfoam-5.x. I the tutorial case, in transportProperties, I found rhoInf [1 -3 0 0 0 0 0] 1.2; I am not clear about the meaning of rhoInf.

Qestion1: How do we modify the density of the fluid phase (e.g. water)?

I also check the createFields.H in the code, and found the following. I have two questions here, please see my comments following by "//"

dimensionedScalar rhoInfValue
(
"rhoInf",
dimDensity,
laminarTransport //Questoin 2: what does it mean here?
);

volScalarField rhoInf
(
IOobject
(
"rho", // Question3: why this "rho", and volScalarField is rhoInf? What does it mean?
runTime.timeName(),
mesh,
IOobject::NO_READ,
IOobject::AUTO_WRITE
),
mesh,
rhoInfValue
);

Many thanks if you can help!

Best,
Titi Sui
