Hello all,
I am pretty new to OpenFOAM and have been playing with the actuationDiskSource function to simulate a wind turbine using pimpleFoam. My case is fairly simple: a rectangular tunnel of 100m in x direction and 10m X 10m cross sectional area in x-y directions. Flow is in +x direction. I am trying to place a single wind turbine in the middle of the tunnel (disk center at <50,5,5>).
After examining the turbineSiting tutorial, two files has caught my attention:

• system/topoSetDict
• constant/fvOptions

The settings I have in those files are;

• system/topoSetDict

actions
(
    // actuationDisk1
    {
        name    actuationDisk1CellSet;
        type    cellSet;
        action  new;
        source  boxToCell;
        sourceInfo
        {
            box (50.5 0 0) (54.8 10 10);
        }
    }
    {
        name    actuationDisk1;
        type    cellZoneSet;
        action  new;
        source  setToCellZone;
        sourceInfo
        {
            set actuationDisk1CellSet;
        }
    }
);

• constant/fvOptions

disk1
{
    type            actuationDiskSource;

    fields      (U);

    selectionMode   cellSet;
    cellSet         actuationDisk1;
    diskDir         (-1 0 0);    // Orientation of the disk
    Cp              0.386;
    Ct              0.58;
    diskArea        7.07; // area of radius 1.5m
    upstreamPoint   (50 5 5);
}

With these settings, I do not see the effect of actuator disk. Any other settings to adjust, or something wrong?

Thanks in advance.
