Hi,

I want to simulate an Vortex induced over a cellSet in my domain. Therefore, I added the momentoumSource() compatibility to my solver and recompiled it. So far so good.

Question is about my SourceDict itself, I want to access the created faceZone and add there some velocity distribution over the cells.

This is my Dictionary so far:

vortexSource
{
    {
    type vectorSwakImplicitSource;

    active true;
    timeStart 0;
    duration 5;
    selectionMode faceZone;
    cellZone    vortexZone;

    variables (
        "xMin=min(pos().x);"
        "xMax=max(pos().x);"
        "yMin=min(pos().y);"
        "yMax=max(pos().y);"
        "zMin=min(pos().z);"
        "zMax=max(pos().z);"
        "alpha=1;"            
        "r=mag(pow(xMax/2,2)+pow(yMax/2,2));"
        "vx=-0.5*alpha*r;"
        "vy=alpha*r;"
        "vz=1;"
        );
        dimensions [0 1 -2 0 0 0 0];
        expression  "vector(vx,vy,vz)";
    }    
};

The code runs but no Source is induced over the cellSet, it only gives the regular flow results of the internal Field calculated by the solver.

Where is my problem?

Thanks in advance

Which version of swak, which version of OF? Anyway: in my dev-version Examples/BasicSourceSubclasses/pitzDailyWithImplicitSource/constant/sourcesProperties looks like this

plug
{
    type vectorSwakImplicitSource;

    active true;
    timeStart 0;
    duration 1e7;
    selectionMode all;

    vectorSwakImplicitSourceCoeffs {
        switchExplicitImplicit true;

        variables (
            "xMin=0.05;"
            "xMax=0.075;"
            "resist=1e3;"
        );

        expressions {
            U "(pos().x<xMax && xMin<pos().x ? -resist : 0)";
        }

        dimensions [0 0 -1 0 0 0 0];
    }
}
