Pointwise to OpenFOAM: how to handle internal face
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:
Code:
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)
frontAndBack 20000 20502 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?
