FOAM FATAL ERROR:
mesh flux field does not exist, is the mesh actually moving?
From function const Foam::GeometricField<double, Foam::fvsPatchField, Foam::surfaceMesh> &Foam::fvMesh:: phi() const
in file fvMesh/fvMeshGeometry.C at line 429.

I am trying to refine mesh based on alpha.ndodecane (fuel in diesel engine) by using dynamicRefinefvMesh class and the solver used is 'interPhaseChangeDyMFoam'. But I am gettting above mentioned error every time, I run the simulation.

I am also posting the 'dynamicMeshDict' file that I have written for this simulation.

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dynamicFvMesh dynamicRefineFvMesh;


// Refinement
dynamicRefineFvMeshCoeffs
{
// Refine every refineInterval timesteps
refineInterval 5;

// Maximum refinement level (starts from 0)
maxRefinement 4;
unrefineLevel 10;
nBufferLayers 1;

// Maximum cell limit (approximate)
maxCells 500000000;

// volScalarField to base refinement on
field alpha.ndodecane;


// Which cells to un/refine: based on point values (simple averaging).
// - refine pointCells of point value inbetween minLevel..maxLevel
// - unrefine pointCells that are within nBufferLayers of points marked
// for refinement.

//maxLevel 0.8762;
lowerRefineLevel 0.001;
upperRefineLevel 0.999;



// Fluxes to adapt. For newly created faces or split flux
// gets estimated from an interpolated volVectorField ('velocity')
// First is name of the flux to adapt, second is velocity that will
// be interpolated and inner-producted with the face area vector.
correctFluxes
(
(phi U)
(nHatf none)
(rhoPhi none)
(ghf none)
);

// Write the refinement level as a volScalarField
dumpLevel true;
}

Can anyone help me know the reason of this error and if the inputs in 'dynamicMeshDict' are correct or not.
