CFD Online Discussion Forums - programing problem: autoPtr<incompressible::RASModel> ...

Hi everybody,

I want to know what is the role of autoPtr<..::..> and what should I place in <..::..> and how can I find out the arrangement of it?

here is a example (buoyantBoussinesqSimpleFoam solver):

Code:

    singlePhaseTransportModel laminarTransport(U, phi);

    

    autoPtr<incompressible::RASModel> turbulence

    (

        incompressible::RASModel::New(U, phi, laminarTransport)

    );

I find in OpenFOAM/OpenFOAM-2.1.0/src/turbulenceModels/incompressible/turbulenceModel and at turbulenceModel.C the following:

Code:

autoPtr<turbulenceModel> turbulenceModel::New

(

    const volVectorField& U,

    const surfaceScalarField& phi,

    transportModel& transport,

    const word& turbulenceModelName

)

and

Code:

    return autoPtr<turbulenceModel>

    (

        cstrIter()(U, phi, transport, turbulenceModelName)

    );

but how can I understand what should I write in < >???????

I'm using viscoelasticFluidFoam and I'm trying to read some parameter from OpenFOAM/OpenFOAM-2.1.0/src/transportModels/viscoelastic/viscoelasticLaws/Giesekus, the Giesekus.C file.

when I see the buoyantBoussinesqSimpleFoam solver, I thought that the key is the autoPtr but How???

please help me!
any hints or tips appreciated.

Thanks,
Mostafa
