CFD Online Discussion Forums - rho in fvc::flux

Hi all, I'm looking for the way the give the fvc::flux a density with a different name of "rho", from the code we have that when we're dealing with a mass flux, then the following code is executed (PhiScheme.C):

Code:

00069     if (this->faceFlux_.dimensions() == dimDensity*dimVelocity*dimArea)

00070     {

00071         const volScalarField& rho =

00072             phi.db().objectRegistry::template lookupObject<volScalarField>

00073             ("rho");

00074 

00075         tUflux = this->faceFlux_/fvc::interpolate(rho);

00076     }

so the problem density is obtained from the objectRegistry. The issue is that it seems FOAM only search for "rho" named density.

Is it possible to give a different name for the density in the case of fvc::flux operataror like in BC's?

Thanks in advance.
