Hello together,

I have a question about a certain line of createFields.H of chemFoam:

http://foam.sourceforge.net/docs/cpp/a03249_source.html

00026     Info<< nl << "Reading thermophysicalProperties" << endl;
00027     autoPtr<psiChemistryModel> pChemistry(psiChemistryModel::New(mesh));
00028 
00029     psiChemistryModel& chemistry = pChemistry();
00030     scalar dtChem = refCast<const psiChemistryModel>(chemistry).deltaTChem()[0];

What exactly is pChemistry? I see that psiChemistryModel is an abstract class and instances cannot be created using the standard constructor, right?
However, in line 29, what is pChemistry(); doing ?

Actually, what I want to do is: create a list of autoPtr<psiChemistryModel> and then perform line 29 for each entry of that list.
Here is my code which does not work:

// this part works
pChemistry.set
        (
            i,
            autoPtr<psiChemistryModel>
            (
                psiChemistryModel::New
            (
                fluidRegions[i]
            )
            ).ptr()
        );

// but this step does not work
psiChemistryModel& chemistry = (pChemistry[i])();

This results in the error:

fluid/createFluidFields.H:108: error: no match for call to ‘(Foam::psiChemistryModel) ()’

Okay, found it. Just had to look at the implementation of
PtrList, List and psiChemistryModel
