This error message may be misleading, "rhoName" is not an input (just "rho").

Can also have logic like this:
// Incompressible { const incompressible::turbulenceModel* model = mesh.lookupObjectPtr<incompressible::turbulenceModel> ( turbulenceModel::propertiesName ); if (model) { return tmp<volSymmTensorField> ( new volSymmTensorField(rho() * model->devRhoReff()) ); } } // Compressible { const compressible::turbulenceModel* model = mesh.lookupObjectPtr<compressible::turbulenceModel> ( turbulenceModel::propertiesName ); if (model) { return tmp<volSymmTensorField> ( new volSymmTensorField(model->devRhoReff()) ); } } FatalErrorInFunction << " The turbulence model is not found in the database." << exit(FatalError); return tmp<volSymmTensorField>();Edited by Mark OLESEN
