Hello all!

Is there a way to check if a volumetric scalar field has already been declared?

I have the following code for a function:

Foam::tmp<Foam::volScalarField>
Foam::viscosityModels::tempPowerLaw::calcNu() const
{
    const volScalarField& T = U_.mesh().lookupObject<volScalarField>("T");
    return a_*exp(b_*T) + c_*exp(d_*T);
}

And I want to lookup the value of T only if T has already been defined.

Any suggestions?

Thanks in advance!!

just in case someone looks at this thread:

U_.mesh().foundObject<volScalarField>("T")

returns true if T is found in the database and false if not
