HI Gmshers,

I hope that you are all fine. I have faced getting an empty patch, even though I have defined it when I used checkMesh command. I am not so sure why I keep getting it. Can somebody explain how can I solve it.

Code:
Checking patch topology for multiply connected surfaces...
    Patch               Faces    Points   Surface topology                  
    front               27880    28222    ok (non-closed singly connected)  
    top                 205      412      ok (non-closed singly connected)  
    inlet               136      274      ok (non-closed singly connected)  
    back                27880    28222    ok (non-closed singly connected)  
    Shroud              0        0        ok (empty)                        
    bottom              205      412      ok (non-closed singly connected)  
    outlet              136      274      ok (non-closed singly connected)  

Checking geometry...
    Overall domain bounding box (0 -6 0) (12 6 1)
    Mesh (non-empty, non-wedge) directions (1 1 1)
    Mesh (non-empty) directions (1 1 1)
    Boundary openness (-3.96508e-17 -1.32169e-17 3.70639e-15) OK.
 ***High aspect ratio cells found, Max aspect ratio: 11049.7, number of cells 3786
  <<Writing 3786 cells with high aspect ratio to set highAspectRatioCells
    Minimum face area = 3.7515e-08. Maximum face area = 0.34119.  Face area magnitudes OK.
    Min volume = 3.7515e-08. Max volume = 0.048118.  Total volume = 144.  Cell volumes OK.
    Mesh non-orthogonality Max: 86.5763 average: 9.84465
   *Number of severely non-orthogonal (> 70 degrees) faces: 36.
    Non-orthogonality check OK.
  <<Writing 36 non-orthogonal faces to set nonOrthoFaces
    Face pyramids OK.
    Max skewness = 0.74544 OK.
    Coupled point location match (average 0) OK.

Failed 1 mesh checks.
Thanks in advance,
