Hello,

After successful compilation of OpenFOAM-1.6-ext on Ubuntu 12.04 64bit, i tried to add a compressible LES turbulence model to the library, i.e. kOmegaSSTSAS turbulence model. I managed to compile this model and use it within versions of OpenFOAM 2.0, and I got nice results. Making minor changes to the code, I almost have succeeded to compile it within the OpenFOAM-1.6-ext. The following error message appears after running command "wmake" or "wmake libso" (short version):

error: cannot allocate an object of abstract type ‘Foam::compressible::LESModels::kOmegaSSTSAS’
kOmegaSSTSAS/kOmegaSSTSAS.H:77:7: note: because the following virtual functions are pure within ‘Foam::compressible::LESModels::kOmegaSSTSAS’:


Or full version:

Actually, I've found the problem...after removing the following line from kOmegaSSTSAS.C, the building goes successfully:

addToRunTimeSelectionTable(LESModel, kOmegaSSTSAS, dictionary);


I've been comparing kOmegaSSTSAS.C & kOmegaSSTSAS.H with other turbulence model files, but without a little success...

I'm not sure if I have to add some lines to files and options files in Make folder...?


Regards!

After two weeks of searching for a solution, the problem was solved by adding the following function definition in kOmegaSSTSAS.H file:

//- Return thermal conductivity
virtual tmp<volScalarField> alphaEff() const
{
return tmp<volScalarField>
(
new volScalarField("alphaEff", alphaSgs_ + alpha())
);
}

Hi Bojan,

I have encountered same problem when I am trying to implement an old code to OpenFoam 3.0 the message I am receiving is


error: cannot allocate an object of abstract type ‘Foam::MyEvaporationStA<Foam::ReactingCloud<Foam:: ThermoCloud<Foam::KinematicCloud<Foam::Cloud<Foam: :ReactingParcel<Foam::ThermoParcel<Foam::Kinematic Parcel<Foam:article> > > > > > > >’
return autoPtr< baseType >(new baseType##Type parList); \
^
MyEvaporationStA is my own evaporation model which is under src/Lagrangian/intermediate/submodels/Reacting/PhaseChangeModels. I am just wondering how did you determine what virtual member needs to be added to the .C file.

Thanks a lot for your help

Hi Leofang,

Actually, I have found problem inside of my error log, you can see it in my post. It is exactly at the end of error log:

Foam::compressible::LESModel::alphaEff() const
lnInclude/LESModel.H:116:9: warning: control reaches end of non-void function [-Wreturn-type]
make: *** [Make/linux64Gcc46DPOpt/kOmegaSSTSAS.o] Error 1


Best regards!

Thanks for your reply Bojan. Unfortunately I still couldn't figure out how to change my source code to mitigate this problem. For your case do you remember why do your have to add virtual function to your header file?

[Bojan]

Hi,

I don't remember exactly, but I think I had to add the virtual function since it was defined in the base class of LES models, called: "class LESModel"
