[OF 6] Outputting enthalpies by reavtingFoam

Dear all,

Hello everyone, thank you for viewing my post.
I'm a beginner of OpenFOAM and C++.

I'm trying to simulate combustion by using reactingFoam in OpenFOAM 6, and I wanna get

1. Total enthalpy
2. Sensible enthalpy
3. Enthalpy of formation

from "janafThermo" class. Then, I add some functions into createFiselds.H as shown below.

Code:

#include "janafThermo.H"

volScalarField& p = thermo.p();

scalar Ha = Foam::janafTermo<EquationOfState>::Ha(p, T);
scalar Hs = Foam::janafTermo<EquationOfState>::Hs(p, T);
scalar Hc = Foam::janafTermo<EquationOfState>::Hc(p, T);

volScalarField Ha
(
    IOobject
    (
     "Ha",
     runTime.timeName(),
        mesh
     ),
    Ha
    //    bsm.Ha()
 );

volScalarField Hs
(
    IOobject
    (
     "Hs",
     runTime.timeName(),
        mesh
     ),
    //    bsm.Hs()
    Hs
);

volScalarField Hc
(
    IOobject
    (
     "Hc",
     runTime.timeName(),
        mesh
     ),
    //    bsm.Hc()
    Hc
 );

//--------------------------------------

But I got the error message like

Code:

 from reactingFoam_H.C:48:
./createFields.H: function ‘int main(int, char**)’ 内:
./createFields.H:31:13: error: ‘EquationOfState’ has not been declared

     (

 scalar Hs = EquationOfState::Hs(p, T);// const;
        ^
./createFields.H:63:5: error: conflicting declaration ‘Foam::volScalarField Hc’
     (
     ^
./createFields.H:33:8: error: ‘Hc’ has a previous declaration as ‘Foam::scalar Hc’
 scalar Hc = EquationOfState::Hc(p, T);// const;
        ^

.

.

So, please tell me the correct way to declare EquationOfState.

Best regard,

Thank you.
