CFD Online Discussion Forums - Writing a wallGradT

Hello fellow openfoam-users,

I'm trying to modify wallGradU to write the sn-gradient of scalar T at the wall calculated by scalarTransportFoam.

It seems to be very straightforward, it compiles and runs but I want to make sure the results are correct.
Here is what I did:

Im creating an IOObject,
and an object wallGradT:

Code:

            volScalarField wallGradT

            (

                IOobject

                (

                    "wallGradT",

                    runTime.timeName(),

                    mesh,

                    IOobject::NO_READ,

                    IOobject::AUTO_WRITE

                ),

                mesh,

                dimensionedScalar

                (

                    "wallGradT",

                    T.dimensions()/dimLength,

                    0

                )

            );

and calculating the surface-normal gradient just as in wallGradU:

Code:

wallGradT.boundaryField()[patchi] = -T.boundaryField()[patchi].snGrad();

Is this the right way?
I want to make sure I'm getting correct results..

Thanks in advance!
