Dear All,

I am recently reading some pieces of the reactingEulerFoam solver from OpenFOAM 3.0.1. When I read the file "HeatAndMassTransferPhaseSystem.C", I did not understand the following:

template<class BasePhaseSystem>
Foam::tmp<Foam::volScalarField>
Foam::HeatAndMassTransferPhaseSystem<BasePhaseSystem>::dmdt
(
    const phasePairKey& key
) const
{
    const scalar dmdtSign(Pair<word>::compare(dmdt_.find(key).key(), key));

    return dmdtSign**dmdt_[key];
}

Should the highlighted line be "dmdtSign*dmdt_[key];"? Thank you so much!
