Hello Foamers,

i was struggling with normalToFace selection in topoSetDict. Let's say i just have a faceZone with the shape of a box. I want to "subtract" only one face of that box from that faceZone. So my topoSetDict looks like this:

actions
(
    {
        name    f0;
        type    faceSet;
        action  new;
        source  zoneToFace;
        zone    kleine_box;
    }

    {
        name    f0;
        type    faceSet;
        action  subtract;
        source  normalToFace;
        normal    (0 1 0);
        cos     0.3;
    }
    
    
    {
        name    f1;
        type    faceZoneSet;
        action  new;
        source  setToFaceZone;
        faceSet  f0;
    }
     
);

I'm ending up with subtracting the both faces in y-axis (see the screen shot), where i actually want to subtract only one of them. Is it possible? Could someone please help me with a hint?

Thanks in advance.
