[T.D.]

Hi Foamers,

the problem is how to add the Field "T" to an existing viscosityModel.

I found in the threads that we need to add the code:

const volScalarField& T = U_.mesh().lookupObject<volscalarField>("T");

But where to add it exactly please? its not clear?

and in Private member Functions when calculating and returning the new calcNu() const

how must we use T in which form "T" or "T_", what is the difference?

thanks a lot
