hi together,

i think it 's very simple question. I tested the fan BC and made a case. there i get four fans.
The problem is, that just two of them have the correct direction (picture).
The other two fan's are wrong. I tested many things but don 't get it solved (just i set 2 of them to cyclic --> other picture)
And i am not good in reading the code :/ so I am not sure what to do (till now).

dimensions      [0 2 -2 0 0 0 0];

internalField   uniform 0;

boundaryField
{
    internalWall
    {
        type            zeroGradient;
    }
    fan1      
    {
        type            fan;
        patchType       cyclic;
        f List<scalar>  2 (0.1 1.0);
        value           uniform 0;
    }
    fan3      
    {
        type            fan;
        patchType       cyclic;
        f List<scalar>  2 (0.1 1.0);
        value           uniform 0;
    }
    fan2      
    {
        type            fan;
        patchType       cyclic;
