Hello,

I'm trying to compile a kEpsilon template (https://github.com/OpenFOAM/OpenFOAM...lon/kEpsilon.C on OpenFOAM 5.x) and am encountering two errors, which are described in the link: https://paste.ubuntu.com/p/DHHHqrgcnz/

It's a bit difficult to explain my goal, but believe me, it's very important to me. When I comment the lines from 144 to 208 (kEpsilon.C), I can compile the solver avoiding ERROR 1.
I can compile (avoiding the ERRO2 described in the link) the solver when I comment lines 254 and 256 (kEpsilon.C).

I hope you can help me.

From you error I assume you took a kEpsilon model from versions prior to 3.0 and tried to compile it with a newer version. In the newer versions (from 3.0 on I guess) you need to write epsEqn.ref().relax();


Have a look at https://www.openfoam.com/documentati...8C_source.html

Thanks, I was able to compile (... yes, the version is 2.4.x).

Now there is only one ERROR to solve my problem...

[mAlletto]

can you post the error in this thread?

[gu1]

Thank you very much for your attention ... it's very important to me.

[mAlletto]

You have to write probably something like this->U_ instead of U_

[gu1]

I was able to solve my problem Michael (replaces U.time().timeName(), with runTime_.timeName(),.. I hope this solution is correct.). Thank you very much.
But now I've got a new problem ... I've created a way to read an external library (it's highlighted below):

turbulenceModel::turbulenceModel
(
const volVectorField& U,
const surfaceScalarField& phi,
const dictionary& dict
)
:
IOdictionary
(
IOobject
(
"stressProperties",
U.time().constant(),
U.db(),
IOobject::MUST_READ,
IOobject::NO_WRITE
)
),
rho_(dict.lookup("rho")),
tau_(dict.lookup("lambda")),
lawPtr_(RASModel::New(word::null, U, phi, subDict("stress")))
{}

...Even after compiling successfully, when I run the solver, it shows the error:

kEpsilonTurbulentFoam: symbol lookup error: kEpsilonTurbulentFoam: undefined symbol: _ZN4Foam17viscoelasticModelC1ERKNS_14GeometricFiel dINS_6VectorIdEENS_12fvPatchFieldENS_7volMeshEEERK NS1_IdNS_13fvsPatchFieldENS_11surfaceMeshEEE

Funny that he had previously presented a similar error...:

$ kEpsilonTurbulentFoam

kEpsilonTurbulentFoam: symbol lookup error: /home/cae/OpenFOAM/cae-5.0/platforms/linux64GccDPInt32Opt/lib/libturbkEpsilonModel.so: undefined symbol: _ZN4Foam15RASModel8typeName

Can you solve any of these? Especially the last...

[gu1]

I still get the error below if you can help me...:

$ kEpsilonTurbulentFoam

kEpsilonTurbulentFoam: symbol lookup error: /home/cae/OpenFOAM/cae-5.0/platforms/linux64GccDPInt32Opt/lib/libturbkEpsilonModel.so: undefined symbol: _ZN4Foam15RASModel8typeName

I tried everything I read in the forums but it did not work out.

EDIT1: I discovered some things about the error...
... in the kEpsilon.C:

namespace Foam
{
defineTypeNameAndDebug(kEpsilon, 0);
// addToRunTimeSelectionTable(RASModel, kEpsilon, dictionary); //error!
}

If I compile with this commented line, it compiles right, BUT... when I try to compile the solver that fetches that library (a solver based on the PISO algorithm) it gives the following error:

/home/cae/OpenFOAM/cae-5.0/platforms/linux64GccDPInt32Opt/lib/libkEpsilonModel.so: undefined reference to para `Foam::RASModel::New(Foam::word const&, Foam::GeometricField<Foam::Vector<double>, Foam::fvPatchField, Foam::volMesh> const&, Foam::GeometricField<double, Foam::fvsPatchField, Foam::surfaceMesh> const&, Foam::dictionary const&)'

If I compile with the uncommented line, it does not compile (kEpsilon.C) ... it throws error.

[mAlletto]

probably you tried to follows the steps in tutorials how to add a new turbulence model for OF versions prior to 3.0


In this blog http://hassankassem.me/posts/newturbulencemodel/ it is described how to do it for versions from 3.0 on
