Hello everyone,

I'm wondering about why the coalChemistryFoam solver includes the the $(FOAM_SOLVERS)/combustion/reactingFoam folder in Make/options file. After remove the inclusion, the following warning is given during the compiling process.

In file included from /home/user/OpenFOAM/OpenFOAM-5.x/src/OpenFOAM/lnInclude/postProcess.H:129:0,
from coalChemistryFoam.C:50:
./createFields.H: In function ‘int main(int, char**)’:
./createFields.H:30:23: warning: unused variable ‘T’ [-Wunused-variable]
const volScalarField& T = thermo.T();
^
./createFields.H:31:23: warning: unused variable ‘psi’ [-Wunused-variable]
const volScalarField& psi = thermo.psi();
^

I checked the $(FOAM_SOLVERS)/combustion/reactingFoam folder, and it seemed that none of the files are used by the coalChemistryFoam. In addition, the variables 'T' and 'psi' are used in the files EEqn.H and pEqn.H, which are included in the coalChemistryFoam.C file. Why it still gives the warning saying unused?

Should I ignore the warning? Does the warning cause anything abnormal?

No, I didn't know the reason yet.
