Dear forum,
For my case, I want to simulate a cornering situation for a racecar. To achieve this, a square domain is used, which is then implemented as an MRF. This all works great, however, to simulate the wheels, we also use an MRF zone. This seems to give a problem that openFOAM will not allow cells to be within two cellZones. I have tried to remove the wheel rotation zone from the whole domain, but this yields issues with surfacefeatureExtract dict. So, my question boils down to: "How to implement an MRF zone which is fully enclosed within another MRF zone".
Below I will post relevant parts from the snappyHexMeshDict.log, MRFproperties and snappyHexMeshDict.
snappyHexMesh.log part which shows no cells are located into the rotatingzones for the 4 wheels can be seen in attachment picture.


SnappyHexMesh code for making the cellZones:

       rotatingzoneDomain
        {
            level       (0 0);
            faceZone    rotatingzoneDomain;
            cellZone    rotatingzoneDomain;
            cellZoneInside  inside;
       }    
            rotatingzonerr
        {
            level       (6 7);
            faceZone    rotatingzonerr;
            cellZone    rotatingzonerr;
            cellZoneInside  inside;
       }
       rotatingzonefr
        {
            level       (6 7);
            faceZone    rotatingzonefr;
            cellZone    rotatingzonefr;
            cellZoneInside  inside;
       }
       
       
       rotatingzonerl
        {
            level       (6 7);
            faceZone    rotatingzonerl;
            cellZone    rotatingzonerl;
            cellZoneInside  inside;
       }
       rotatingzonefl
        {
            level       (6 7);
            faceZone    rotatingzonefl;
            cellZone    rotatingzonefl;
            cellZoneInside  inside;
       }

MRFproperties:

    #include "../Setup"
MRF1
{
    cellZone    rotatingzoneDomain;
    active      yes;
    // Fixed patches (by default they 'move' with the MRF zone)
    nonRotatingPatches (inlet outlet lowerWall upperwall rotatingzonefr rotatingzonerr rotatingzonefl rotatingzonerl) ;
    origin        ($X $Y 0);
    axis        (0 0 1);
        omega         $Omega;
}

MRF2
{
      cellZone     rotatingzonefr;

    active      yes;
    // Fixed patches (by default they 'move' with the MRF zone)
    nonRotatingPatches (mhubfr);
    origin        ($WB $YoriginFwheelR $RwheelRoll);
    axis        ($XaxisFwheelR $YaxisFwheelR $ZaxisFwheel);
    omega        $FRwheel;// Rotational speed in rad/s
}

similar for the rest....

Domain with in red the rotatingzones of the wheels can be seen in attachment.
