Hello everyone,

I want to simulate porous media with solid heat transfer.

I am going to add "addTwoEquationsEnthalpy" to hEqn.h

fvScalarMatrix hEqn
(
fvm::div(phi, h)
- fvm::Sp(fvc::div(phi), h)
- fvm::laplacian(turbulence->alphaEff(), h)
==
- fvc::div(phi, 0.5*magSqr(U), "div(phi,K)")
);
pZones.addTwoEquationsEnthalpySource(thermo, gamma, ts, hEqn);
hEqn.relax();
hEqn.solve();
thermo.correct();

Apart from it I should add tsEqn.h equation somewhere in solver folder "I guess so"

fvScalarMatrix tsEqn
(
-fvm::laplacian(kappa,ts)
);
pZones.addTwoEquationsTsSource(thermo, gamma, ts, tsEqn);
tsEqn.relax();
tsEqn.solve();}

Here "kappa" is convection constant and "ts" is temperature of solid.

I just don't know the procedure of adding this equation to the solver. If you could help me, that would be very nice. Thank you.
