Hi all,

Actually I am working on the pointwise official tutorial case 'BackStep'. I export the polyMesh folder and use checkMesh to examine the mesh. I got the following message:

Checking topology...
    Boundary definition OK.
 ***Total number of faces on empty patches is not divisible by the number of cells in the mesh. Hence this mesh is not 1D or 2D.
    Cell to face addressing OK.
    Point usage OK.
    Upper triangular ordering OK.
    Face vertices OK.
    Number of regions: 1 (OK).

Checking patch topology for multiply connected surfaces...
    Patch               Faces    Points   Surface topology                  
    buildingWall        4300     4410     ok (non-closed singly connected)

    inlet               50       102      ok (non-closed singly connected)  
    lowerWall           100      212      ok (non-closed singly connected)  
    outlet              50       102      ok (non-closed singly connected)  
    upperWall           200      402      ok (non-closed singly connected)  

Checking geometry...
    Overall domain bounding box (0 -0.06 0) (0.6 0.42 0.06)
    Mesh (non-empty, non-wedge) directions (1 1 0)
    Mesh (non-empty) directions (1 1 0)
    All edges aligned with or perpendicular to non-empty directions.
    Boundary openness (5.89915e-18 2.79434e-18 1.65293e-16) OK.
    Max cell openness = 1.09092e-16 OK.
    Max aspect ratio = 7.51167 OK.
    Minimum face area = 9e-06. Maximum face area = 0.0013521.  Face area magnitudes OK.
    Min volume = 5.4e-07. Max volume = 4.0563e-06.  Total volume = 0.0162.  Cell volumes OK.
    Mesh non-orthogonality Max: 0 average: 0
    Non-orthogonality check OK.
    Face pyramids OK.
    Max skewness = 4.62963e-09 OK.
    Coupled point location match (average 0) OK.

Mesh OK.

After the solver convergence, I find that the fluid would not go from one block into the other one.
I think the problem is the internal face between the two blocks. OpenFOAM has problems with internal face, do you have any idea on this issue?

Hi, if you still havent solved it, could you post a picture of your mesh indicating where the boundaries are on it? and the boundary definition list (polymesh/boundary)

Hi,

Thank you very much. The problem is solved
