Hi all,
I am trying to implement a model where I need to solve for a number of (3 or 6, depending on the case setup) transport equations. I thought of using a PtrList for this. I followed what is being done in

$FOAM_SRC/thermophysicalModels/reactionThermo/mixtures/basicMultiComponentMixture

for the variable Y.
However, when I add the line

PtrList<volScalarField> Moments_;

in the header file, and the following in the constructor initializer list:

Moments_(nMoments_)

I get the following on compiling:

/home/adhiraj/OpenFOAM/OpenFOAM-1.7.1/src/OpenFOAM/lnInclude/PtrList.C: In copy constructor ‘Foam::PtrList<T>::PtrList(const Foam::PtrList<T>&) [with T = Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh>]’:
MOMIC/MOMIC.H:62:7: instantiated from here
/home/adhiraj/OpenFOAM/OpenFOAM-1.7.1/src/OpenFOAM/lnInclude/PtrList.C:54:9: error: invalid conversion from ‘Foam:: DimensionedField<double, Foam::volMesh>*’ to ‘Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh>*’ [-fpermissive]
make: *** [Make/linux64GccDPOpt/MOMIC.o] Error 1

nMoments_ is of type const label, and it is defined and initialized before Moments_.
Any ideas what is wrong here?

Anyone?
I don't understand why the copy constructor is being called at all.
It seems that the same method works in some classes, and that makes it very confusing.

SOLVED.
I was trying to create a new instance of the object with "new", and that was the problem.
