Hi,

I am running a simulation of a tidal turbine using an actuator disc. The actuator disc source term in openfoam is calculated using a variableScaling method defined in fvOptions

the thrust coefficient is calculated as

 const scalar CtStar = Ct*sqr(magUref/magUdisk);

the source term is calculated as

    // Compute calibrated thrust/power (LSRMTK:Eq. 5)
    const scalar T = 0.5*rhoRef*diskArea_*magSqr(Udisk & diskDir_)*CtStar;

as shownhere

How can I write the value of CtStar for each timestep that is calculated?

I tried to use functionObjLib in control dict but CtStar is not defined in the list of

    testing
    {
        type writeRegisteredObject;
        functionObjectLibs ( "libIOFunctionObjects.so" );
        objectNames ("bananas");
        outputControl     outputTime;
    }

Thank you

Hello,

I was able to write the CtStar at every timestep. It was trivial!!!

I added a line to the fvOptions

    writeToFile     true;

and the result is given as a data file in postprocessing
