Hi All - I am trying to port a dynamic load balancing routine (https://github.com/tgvoskuilen/meshBalancing) that was written for OF2.3.x to OF 2.1.1. The file dynamic RefineBalancedFvMeshTemplates.C file throws a compilation error as such: error: no mathcing function for call to Foam::HashTable<Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh>. This refers to the line "HashTable<GeoField*> flds(this....." around the 9th line below

The code is as follows:

#include "GeometricField.H"
#include "volMesh.H"
#include "fvPatchField.H"

template<class Type>
void Foam::dynamicRefineBalancedFvMesh::correctBoundaries()
{
    typedef GeometricField<Type, fvPatchField, volMesh> GeoField;

    HashTable<GeoField*> flds(this->objectRegistry::lookupClass<GeoField>());

    forAllIter(typename HashTable<GeoField*>, flds, iter)
    {
        GeoField& fld = *iter();
        
        //mimic "evaluate" but only for coupled patches (processor or cyclic)
        // and only for blocking or nonBlocking comms (no scheduled comms)
        if
        (
            Pstream::defaultCommsType == Pstream::blocking
         || Pstream::defaultCommsType == Pstream::nonBlocking
        )
        {
            label nReq = Pstream::nRequests();

            forAll(fld.boundaryField(), patchi)
            {
                if(fld.boundaryField()[patchi].coupled())
                {
                    fld.boundaryField()[patchi].initEvaluate
                    (
                        Pstream::defaultCommsType
                    );
                }
            }

            // Block for any outstanding requests
            if
            (
                Pstream::parRun()
             && Pstream::defaultCommsType == Pstream::nonBlocking
            )
            {
                Pstream::waitRequests(nReq);
            }

            forAll(fld.boundaryField(), patchi)
            {
                if(fld.boundaryField()[patchi].coupled())
                {
                    fld.boundaryField()[patchi].evaluate
                    (
                        Pstream::defaultCommsType
                    );
                }
            }
        }
        else
        {
            //Scheduled patch updates not supported
            FatalErrorIn
            (
                "dynamicRefineBalancedFvMeshTemplates::correctBoundaries"
            )   << "Unsuported communications type "
                << Pstream::commsTypeNames[Pstream::defaultCommsType]
                << exit(FatalError);
        }
    }
}

Anyone have any idea why this would compile just fine in 2.3 and not in 2.1.1?

Thanks much!
Pete
