Hi guys, would be super apprecitae if someone can give a help here

I tried to create cellzone and facezone with snappyhexmesh in order to run dynamic mesh, like rotatingFanInRoom case did. But it didn't create one and I didn't find the reason

Here is how the SHM looks: I created a AMI using searchableBox, and tried to define the cellZone with refinementSurfaces:

Code:
geometry
{
    FRCfull.stl
    {
     	type triSurfaceMesh;
        name bridge;
    }

    busfull.stl
    {
     	type triSurfaceMesh;
        name bus;
    }

    AMI
    {
     	type searchableBox;
        min (39.5 188675 692);
        max (44.7 188682 747);
    }



};

refinementSurfaces
    {
     	bridge
        {
            // Surface-wise min and max refinement level
            level (7 7);

            patchInfo
            {
                type wall;
            }
	}

        bus
     	{
	    // Surface-wise min and max refinement level
            level (7 7);
       patchInfo
            {
             	type wall;
            }
            }
	AMI
	{
            // Surface-wise min and max refinement level
            level (7 7);
            faceType  boundary;
            cellZone  motioncell;
            faceZone  motionface;
            cellZoneInside  inside;
            //insidePoint (41.1 188680 731);
            }


    }
Then, createPatch was used as well. But checkMesh showed:
Code:
Mesh stats
    points:           85813080
    faces:            244567590
    internal faces:   236510331
    cells:            79390494
    faces per cell:   6.0596414
    boundary patches: 19
    point zones:      0
    face zones:       1
    cell zones:       1
.....

Checking topology...
    Boundary definition OK.
    Cell to face addressing OK.
    Point usage OK.
    Upper triangular ordering OK.
    Face vertices OK.
   *Number of regions: 2
    The mesh has multiple regions which are not connected by any face.
  <<Writing region information to "0/cellToRegion"
  <<Writing region 0 with 79273836 cells to cellSet region0
  <<Writing region 1 with 116658 cells to cellSet region1
The cellZone did not created. Also moveDynamicMesh showed:

Code:
--> FOAM FATAL ERROR:
Unable to find cellZone motioncell.  Valid cellZones are:0()

anyone could give me any suggestion? thx
