Hello Foamers,
I'm using fireFOAM model to simulate the pyrolysis in OpenFOAM. In order to include the effect of gaseous species in pyrolysis model, I need to extract the data from another class and implement in the current model as a source term.
The gaseous species are extracted from the class called "basicChemistryModel"

(i) In reactinOneDim.H file, I included,
autoPtr<basicChemistryModel> newChemistry_; //basicChemistryModel is the class from where data need to be extracted

(ii) In reactinOneDim.C file, I added,
dataExtracted_ = newChemistry_->Sh()(); // Sh()() is the data extracted from the class basicChemistryModel

(iii) In energy equation, the source file is summed up as,

fvScalarMatrix hEqn
(
fvm::ddt(rho_, h_)
- fvm::laplacian(alpha, h_)
==
dataExtracted_ //SOURCE TERM
);

There found no issues with compilations. But while running the case, I got this following error as,

//************************************************** ******//
--> FOAM FATAL ERROR:

From function Foam::autoPtr<T>:perator->()

I have checked about this error in forums, but I couldn't able to get any ideas. Kindly someone share their thoughts.
Thank you

Hi,

Have you been able to figure out the problem

[Kummi]

In order to extract data from the particular class, I have opted autoPtr declaration format. In the beginning, the class "basicChemistryModel" was fitted in inappropriate way. The reason why it leads to error - object type error.
Later I have fitted suitable class "solidChemistryModel", which eliminates the error

autoPtr<solidChemistryModel> solidChemistry_;

Thank you
