Hi,
I'm fairly new to openFoam and I'm trying to simulate a 2D ABL flow over a single turbine and a single sinusoidal hill. The turbine is located just upstream of the hill. I've used the turbineSiting tutorial as a template for this, and have successfully meshed my own geometry. I went from a 3D to 2D mesh with snappyHexMesh by using extrudeMesh and createPatch (as in the wingMotion tutorial), so now my side patches are set as empty.
I can converge on a solution okay and the boundary layer appears correctly. I don't however think the solver is recognising the presence of the turbine. The effect seems almost negligibly different from an equivalent simulation with no turbine when I view the results. If I adjust the pressure and thrust coefficients in fvOptions, there is no change to the solution. Would I be correct in saying that it is through fvOptions that I control the strength of the momentum source in the flow, or should I be looking elsewhere?

fvOptions:

disk1
{
    type            actuationDiskSource;
    variant         variableScaling;
    selectionMode   cellSet;
    cellSet         actuationDisk1;
    diskArea        0.04;
    diskDir         (1 0 0);
    writeToFile     true;
    sink            false;
    Cp              0.5;
    Ct              0.75;
    monitorMethod   points;
    monitorCoeffs
    {
        points
        (
                (-0.1 0.125 0.04)
        );
    }
   }

initialConditions:

flowVelocity         (10 0 0);
pressure             0;
turbulentKE          0.1275;
turbulentEpsilon     0.3733;

turbulenceProperties:

simulationType RAS;

RAS
{
    RASModel            kEpsilon;

    turbulence          on;

    printCoeffs         on;

    kEpsilonCoeffs
    {
        Cmu         0.09;
        C1          1.44;
        C2          1.92;
        sigmaEps    1.11; //Original value:1.44
}
}

Thank you!

I'm also attaching here a picture of the mesh (where you can see the refined region for the actuator disk) and the streamwise velocity field.

After having as scientifically as possible changed the variables within the fvOptions file, I still can't simulate a change in the actuator disk effect. This also happens on the unaltered turbineSiting tutorial. Is there a way I can check that fvOptions is properly being read by the solver?


I have now switched to using CFDDFC on amazon's web services to run my simulations. I can confirm that there is something wrong with the mac installation files, as I can now run the simulations perfectly with my chosen geometry.
