Hello everyone!

I'm trying to solve a problem with a gradient but I can't figure out how to get the value of a field, in this case Temperature, adjacent to a face.
So far I wrote this:

const scalarField& Tp = 
          patch().lookupPatchField<volScalarField, scalar>("T"); 
const scalarField& Tc = 
          patch().lookupPatchField<volScalarField, scalar>("T").internalField();
const scalarField& deltaInv = patch().deltaCoeffs(); 
const scalarField gradT_ = - (Tp-Tc)*deltaInv;

But if I write the size of Tp and Tc I get different values (namely 2000 and 80000).


I'm sure I'm doing something wrong with the "internalField()" member function, but ... what? Do you have an idea?

Thank you!
