I am trying to implement a coupled Lagrangian-interFoam solver in OF-6 where I want to refine the mesh in two-phase interface region using the dynamicFvRefineMesh option.

However, I encounter the following fatal error as soon as the refinement is done before first timestep.

--> FOAM FATAL ERROR:
Global positions are not available. Cloud::storeGlobalPositions has not been called.

    From function void Foam::Cloud<ParticleType>::autoMap(const Foam::mapPolyMesh&) [with ParticleType = Foam::CollidingParcel<Foam::KinematicParcel<Foam::particle> >]
    in file /opt/openfoam6/src/lagrangian/basic/lnInclude/Cloud.C at line 349.

FOAM exiting

I tried to add the following lines to my solver loop:

          if (pimple.turbCorr())
            {
                turbulence->correct();
            }
        }

        Info<< "Evolving "<< kinematicCloud.name() <<endl;
        kinematicCloud.evolve();
        kinematicCloud.storeGlobalPositions();
        runTime.write();

        Info<< "ExecutionTime = " << runTime.elapsedCpuTime() << " s"
            << "  ClockTime = " << runTime.elapsedClockTime() << " s"
            << nl << endl;

The code compiles but the same problem persists.
The function storeGlobalPositions() is defined in Cloud.H, which is referenced by basicKinematicCollidingCloud.H. If I try to call it like this:

 Cloud::storeGlobalPositions();

The compiler throws an error that

interFlow.C:161:2: error: ‘template<class ParticleType> class Foam::Cloud’ used without template parameters
   Cloud::storeGlobalPositions();

I am new to the concept of templates so could someone help me understand and formulate the correct way to call the above function? The kinematicCloud object itself is defined like this in createFields.H:

//Initialize basicKinematicCollidingCloud

const word kinematicCloudName
(
    args.optionLookupOrDefault<word>("cloudName", "kinematicCloud")
);
Info<< "Constructing kinematic cloud "<< kinematicCloudName <<endl;

basicKinematicCollidingCloud kinematicCloud
(
    kinematicCloudName,
    rho,
    U,
    mu,
    g
);

Thanks for taking time to read this.
