Lagrangian solver(trackingData& td)

Dear friends
I have developed the parcel and kinematicCloud in MPPICFoam in order to contain the Oxygen and Nitrogen mass in each parcel. My library and code compiles correctly, but when I run the code, I got an error which says "Segmentation fault (core dumped)" and the error happens exactly at the red line below;

Code:

template<class CloudType>

void Foam::KinematicCloud<CloudType>::evolve()

{

    Info<<"KinematicCloud.C-evolve-FFD1"<<endl;



    if (solution_.canEvolve())

    {

        typename parcelType::trackingData td(*this);



        solve(*this, td);

    }

    Info<<"KinematicCloud.C-evolve-FFD2"<<endl;

}

Could you please explain to me what is "trackingData& td" and where it is defined and how can I change it?

Thanks,
Farzad

You can find "trackingData" in "src/lagrangian/intermediate/parcels/Templates/KinematicParcel/KinematicParcelTrackingData.H", as the filename suggests. It basically holds the interpolators and values for the continuous phase fields.
