CFD Online Discussion Forums - gather parallelized fields

Hi,
I'm trying to gather fields of boundary patches, which are distributed on multiple processors. I want to due this to generate specialised output using function objects.

I found a function that seems to do exactly what I need ( combineFields(...) ).
I included an adapted version of this function and included it into my functionObject.

Everything compiles smoothly but when the function is called I get an error.

The function looks like this:

Code:

template<class Type>

const tmp<Foam::Field<Type> > turboMonitorPool::combineFields

(

    const Field<Type>& field

) const

{

    List<Field<Type> > allValues(Pstream::nProcs());



    allValues[Pstream::myProcNo()] = field;



    Pstream::gatherList(allValues);



    if (Pstream::master())

    {

        return tmp<Field<Type> >

        (

            new Field<Type>

            (

                ListListOps::combine<Field<Type> >

                (

                    allValues,

                    accessOp<Field<Type> >()

                )

            )

        );

    }

    else

    {

        return tmp<Field<Type> >

        (

            new Field<Type>

            (

                field

            )

        );

        //return field;

    }

}

This is the call:

Code:

        

const fvMesh& mes = refCast<const fvMesh>(obr_);

const tmp< Field<vector> > myCf = combineFields(mes.Cf().boundaryField()[0] );

and this is the error message:

Code:

symbol lookup error: /graz/home/openfoam/OpenFOAM/openfoam-1.6-ext/lib/linux64GccDPOpt/libturboMonitor.so: undefined symbol: _ZNK4Foam16turboMonitorPool13combineFieldsINS_6VectorIdEEEEKNS_3tmpINS_5FieldIT_EEEERKS7_

So the argument that I'm passing is wrong, although I'm passing a field of Type (A special field of type).

Hope someone knows the answer to this one...

Cheers,
Michi
