Total temperature boundary cannot be set in the Tt file when using hy2foam

[Rockyuo666]

Total temperature boundary cannot be set in the Tt file when using hy2foam,but can be set in Tv file.Why it happens?

I am using hyStrath code in OpenFOAM-v1706. You can see the following code of fixed2EnergyFvPatchScalarField::updateCoeffs() in src/thermophysicalModels/strath/strathReactionThermo/reactionThermo/derivedFvPatchFields/fixedEnergy/fixed2EnergyFvPatchScalarField.C
` if (updated())
{
return;
}

//Info<< "fixed2Energy is used for patch called "
//    << patch().name() << endl;

const multi2Thermo& multiThermo = multi2Thermo::lookup2Thermo(*this);

const label patchi = patch().index();

const fvPatchScalarField& pw = multiThermo.p().boundaryField()[patchi];
const fvPatchScalarField& Tw = multiThermo.T().boundaryField()[patchi];

tmp<scalarField> thet(new scalarField(pw.size()));
tmp<scalarField> thevel(new scalarField(pw.size()));

scalarField& het = thet.ref();
scalarField& hevel = thevel.ref();

het = 0.0;
hevel = 0.0;

forAll(thermo_.composition().species(), speciei)
{
    const fvPatchScalarField& spYw =
        thermo_.composition().Y(speciei).boundaryField()[patchi];
    const fvPatchScalarField& spTvw =
        thermo_.composition().Tv(speciei).boundaryField()[patchi];

    het += spYw*thermo_.composition().het(speciei, pw, Tw, patchi);
    hevel += spYw*thermo_.composition().hevel(speciei, pw, spTvw, patchi);
}

operator==(het + thevel);

fixedValueFvPatchScalarField::updateCoeffs();`

Compared with the similar code in the original OpenFOAM-v1706 code, there seems to be no code like "Tw.evaluate();", I think this is the reason.
