Hi everyone,
I am coding a new specie transport library in OpenFOAM. I need to access density which is calculated by the 'equation of state'. I have tried using the following code but no success...

scalar volVectorField& rho_ = rho().db().lookupObject<volVectorField>("rho");

Any help in this regard please.

I get the following error with above code...

error: expected initializer before ‘&’ token

Your code looks pretty strange on two accounts. First you have declared the variable as a "scalar volVectorField" - just wrong. You want "volScalarField" as the type. Second, you appear to be working from rho(), so why do you need to look that up via the database?
