Hi,

My project work is on oxidation reaction of metal with steam. For this purpose, I have modified chtMultiRegionFoam (version 6) by including pyrolysis model. But this pyrolysis model takes care only below reaction
solid1 = solid2 + gas.
The reaction that I am trying to solve is solid1 + gas1 = solid2 + gas2. For this, I have found reactingOneDim21CharOxi (fireFoam-dev) is suitable. While compiling library function, Below statements are giving troubles.

const label charIndex = solidThermo_.composition().species()["char"];
scalar rhoChar = solidThermo_.composition().rho(charIndex, 10000, 298);

dimensionedScalar Cp0("Cp0", dimEnergy/dimMass/dimTemperature, solidThermo_.composition().Cp(0, 1.0e05, 300.) );
dimensionedScalar Cp1("Cp1", dimEnergy/dimMass/dimTemperature, solidThermo_.composition().Cp(1, 1.0e05, 300.) );

The error is
'class Foam:: autoPtr<Foam:: solidReactionThermo>' has no member named composition

The base class is reactingOneDim instead of reactingOneDim21 which is used in fireFoam-dev.

The constructors used in reactingOneDim are different from reactingOneDim21.

In reactingOneDim - these statements are used :solidThermo_(solidReactionThermo::New(regionMesh( ))), solidChemistry_(basicSolidChemistryModel:: New(solidThermo_())),

while in reactingOneDim21, statements are: solidChemistry_(basicSolidChemistryModel::New(regi onMensh())), solidThermo_(solidChemistry_solidThermo())

Kindly give some insight view about this topic, which will be highly helpful for my research.

Thank you

Hello Archana,

For my topic of research, I combined chtMultiRegionFoam and firFoam (Solid model alone).
As you stated, only [solid1 = solid 2 + gas] defined by default in the reacting one dimensional solid solver. i.e., one solid on the L.H.S and one solid on R.H.S with only 1 gas can be defined. In addition, no stoichiometric coefficients can be defined in solid model unless and until it is defined and declared in solid chemistry model.

I recommend you to refer biomassGasificationFOAM source files below, where you can fit the expected global reaction with coefficients.

Hope it helps. Thank you^^

Thanks. I will look into it.

I hope, you are clear with the error? And you know some of C++ already?

I suppose, in solidReactionThermo (version-6), there is no member function of composition. I am able to compile with OpenFOAM-4, but not with OpenFOAM-6. I am new to C++.

[ankur_garg]

Yes. You are actually right. OpenFOAM4 is much stable version than 6. You can go ahead with 4. Moreover, if you want to learn more through debugging, I would suggest you to use OpenFOAM ESI version like OpenFOAM-v1612+ and more. Build that in debug mode which you can change in etc/nashe file. I hope you are not new to OpenFOAM!

Etc/bashrc. Sorry it was autocorrect, not me!

Thanks Ankur.
