Summary0003343: oldCellCentre calling error when using sets functionObject
DescriptionIn order to monitoring surface elevation in DTBHullMoving case, I have set functionObject in controlDict as follows:

        type sets;
        libs ("");
        writeControl timeStep;
        writeInterval 1;

        interpolationScheme cellPointFace;
        setFormat gnuplot;
        fields (alpha.water);
                type lineUniform; // uniform;
                axis z;
                start (0 -10 -1);
                end (0 -10 1);
                nPoints 100;


when the DTCHull case run with interFoam, I met the following error

Old cell centres have not been stored

    From function virtual const pointField& Foam::polyMesh::oldCellCentres() const
    in file meshes/polyMesh/polyMesh.C at line 1210.

I found that oldCellCentres() member function and oldCellCentresPtr_ memeber variable was introduced since OpenFOAM 7
Also, I found that it looks working if the dynamicFvMesh type is staticFvMesh but it make the above error if dynamicMotionSolverFvMesh.

I could not go further to study the issue but it looks like
   oldCellCentresPtr_ is assigned in movePoints when storeOldCellCentres_ is true.
   but storeOldCellCentres_ is set to true but make error since oldCellCentresPtr_ is empty in oldCellCentres() member function as follows:

const Foam::pointField& Foam::polyMesh::oldCellCentres() const
    storeOldCellCentres_ = true;

    if (!moving_)
        return cellCentres();

    if (oldCellCentresPtr_.empty())
            << "Old cell centres have not been stored"
            << exit(FatalError);

    return oldCellCentresPtr_();

Please check this issue.
