Dear formers,

I use following fvSchemes for a film cooling problem. As attached plots show laminar case of the same problem converges. But I still have concern about the the peak of the pressure residuals. The turbulent case with standard k-epsilon model does not converge. Dose anyone of you can give me any idea. Your help is much appreciated. I am burning weeks for this problem now.

Best regards,
Suranga.

It is unlikely that you will find the problem in the fvSchemes. Also, which solver are you using? What are your tolerances in fvSolution? And, which residuals are you plotting here? Initial, final or what? What are the boundary conditions?

Hi Bernhard,
Thanks for your reply.
Here with I have attached 0 and system directories of my case. Please be kind to go through these and help me. I uses pyFoamPlotWatcher.py to plot residuals and it plots initial residuals.

BR,
Suranga.

I am sorry I couldn't attach the solver in the last post. Here it is. I use modified simpleFoam by adding temperature equation to the general simpleFoam.

Hi Bruno,

I am very sorry if I interpreted the problem wrong. It seems that you got little upset. I am sorry about that. I am also very inexperience in OpenFoam. And I don't understand most of the things in codes. And I am pretty new to CFD too. That is why I have been seeking help in the forum. I just wanted to see whether I am doing right.Anyway here is what I did.

I copied Make directory, pEqn.H, UEqn.H, createFields.H and simpleFoam.C files form /opt/openfoam211/applications/solvers/incompressible/simpleFoam to /home/suranga/OpenFOAM/suranga-2.1.1/applications/solvers/tempSimpleFoam and changed the file name simpleFoam.C to tempSimpleFoam.C.

Then I modified createFields.H as shown below. Modifications are shown in red.
Code:
Info<< "Reading field p\n" << endl;
    volScalarField p
    (
        IOobject
        (
            "p",
            runTime.timeName(),
            mesh,
            IOobject::MUST_READ,
            IOobject::AUTO_WRITE
        ),
        mesh
    );
// temperature field
    
    Info<< "Reading field T\n" << endl;
    volScalarField T
    (
        IOobject
        (
            "T",
            runTime.timeName(),
            mesh,
            IOobject::MUST_READ,
            IOobject::AUTO_WRITE
        ),
        mesh
    );

//end temperature field

    Info<< "Reading field U\n" << endl;
    volVectorField U
    (
        IOobject
        (
            "U",
            runTime.timeName(),
            mesh,
            IOobject::MUST_READ,
            IOobject::AUTO_WRITE
        ),
        mesh
    );

#   include "createPhi.H"


    label pRefCell = 0;
    scalar pRefValue = 0.0;
    setRefCell(p, mesh.solutionDict().subDict("PISO"), pRefCell, pRefValue);


    singlePhaseTransportModel laminarTransport(U, phi);

// laminar prandtl number [Pr]
    
    dimensionedScalar Pr(laminarTransport.lookup("Pr"));
//turbulent Prandtl number [Prt]
    dimensionedScalar Prt(laminarTransport.lookup("Prt"));

    autoPtr<incompressible::turbulenceModel> turbulence
    (
        incompressible::turbulenceModel::New(U, phi, laminarTransport)
    );
And then changed then created a file TEqn.H in tempSimpleFoam directory. (actually I cloned it from some other code but I don't remember what the original application is)
Code:
{
    volScalarField kappaEff
    (
        "kappaEff",
        turbulence->nu()/Pr + turbulence->nut()/Prt
    );

    fvScalarMatrix TEqn
    (
        //fvm::ddt(T) // changed this since simpleFoam is steady state.
      fvm::div(phi, T)
      - fvm::laplacian(kappaEff, T)
    );

   TEqn.relax();

    TEqn.solve();

    //rhok = 1.0 - beta*(T - TRef);
}
Then tempSimpleFoam.C was changed as shown below.
Code:

// ************************************************************************* //
Then in Make/files I change the following.

Hi Suranga,

I've moved some of your posts related to this problem into a single thread. The reason is rather simple, as explained here: http://www.cfd-online.com/Forums/ope...-get-help.html

I see that some people post new questions in active threads cause they think this will attract more readers. Do not do this, since it makes it really hard to search the forum.
About what you wrote in the previous post:

I think I was already too tired yesterday to be upset But put yourself in my shoes: how would you feel if someone simply asked you what is the specific and concrete value to give to "z", so that the following equation is true: "x + y + z = 1"

Now, as for the problem you have... I'm going to have to think a bit on this, gather the information on the whole thread and I'll reply back when I have any news.

In the mean time, if anyone else wants to answer to Suranga, feel free to do so!

Best regards,
Bruno

Hi Suranga,

I don't know what is the problem you're getting, because I was not able to reproduce it. Apparently I'm still missing either "x" or "y", in order to tell you what "z" is!

Attached are the following files:
  • tempSimpleFoam.tar.gz - solver modified somewhat based on your instructions. There is a discrepancy, because you posted a "createFields.H" that refers to "PISO" near the end of the file, but I used the original "SIMPLE".
  • suranga_temp.tar.gz - based on the tutorial "incompressible/simpleFoam/pitzDaily" and on the files you provided.
The final iteration 1000 had this:
Code:
DILUPBiCG:  Solving for Ux, Initial residual = 9.3952e-006, Final residual = 3.09815e-008, No Iterations 2
DILUPBiCG:  Solving for Uy, Initial residual = 9.72644e-005, Final residual = 2.51259e-007, No Iterations 2
GAMG:  Solving for p, Initial residual = 0.000164337, Final residual = 1.4318e-006, No Iterations 14
time step continuity errors : sum local = 7.01076e-006, global = -1.60798e-007, cumulative = -0.0238757
DILUPBiCG:  Solving for T, Initial residual = 0.0313769, Final residual = 8.66675e-005, No Iterations 99
DILUPBiCG:  Solving for epsilon, Initial residual = 1.40552e-005, Final residual = 1.13521e-007, No Iterations 4
DILUPBiCG:  Solving for k, Initial residual = 3.8993e-005, Final residual = 3.73099e-007, No Iterations 3
The residual for T looks rather high, but that's possibly because things were not properly defined somewhere...


So, I suggest that you do the following steps:
  1. If you cannot share the case you're working on, then create a case based on a tutorial that has a similar geometry to yours, similarly to what I did. Then share that case with us here on this thread.
  2. If you do not have convergence problems with that test case, then check the sanity of the mesh on your current case:
    Code:
    checkMesh
    checkMesh -allTopology -allGeometry
Best regards,
Bruno

I am sorry, It seems I have attached details of the wrong file. This is the correct createFields.H which is created for tempSimpleFoam solver.

    );
// temperature field

            mesh,
            IOobject::MUST_READ,
            IOobject::AUTO_WRITE
        ),
        mesh
    );

//end temperature field

    Info<< "Reading field U\n" << endl;
    volVectorField U
    (
        IOobject
        (
            "U",
            runTime.timeName(),
            mesh,
            IOobject::MUST_READ,
            IOobject::AUTO_WRITE
        ),
        mesh
    );

    #include "createPhi.H"


    label pRefCell = 0;
    scalar pRefValue = 0.0;
    setRefCell(p, mesh.solutionDict().subDict("SIMPLE"), pRefCell, pRefValue);

    singlePhaseTransportModel laminarTransport(U, phi);

    // laminar prandtl number [Pr]
    
    dimensionedScalar Pr(laminarTransport.lookup("Pr"));
//turbulent Prandtl number [Prt]
    dimensionedScalar Prt(laminarTransport.lookup("Prt"));

    autoPtr<incompressible::RASModel> turbulence
    (
        incompressible::RASModel::New(U, phi, laminarTransport)

    IObasicSourceList sources(mesh);
And I missed to mention that I defined Pr and Prt in transportProperties dictionary in the case/system directory. It is shown below.

Hi sdharmar,

I have read the TEqn.H that your posted. However I have not understood clearly with your TEqn. What is the kappaEff? Can you give me a mathematical equation to describe it? And I have modified the pisoFoam solver to simulate my film cooling case.
This is my T equation:
Code:
        fvScalarMatrix TEqn
        (
            fvm::ddt(T)
            + fvm::div(phi, T)
            - fvm::laplacian(DT, T)
        );

        TEqn.solve();
Am I right to modify it like this?

Best regards

Hi sdharmar,

I have another question to you. How do you set the value of Prt? Do you have a formula to figure it out?

Regards,
Sunxing
