Mesh Check fails in OpenFoam ????
Hello everyone :)
I am trying to import mesh from fluent to OpenFoam with 'fluentMeshToFoam'. Mesh is OK in fluent but in OpenFoam it getting 'Fail' message. The message is as follow: Create time Create polyMesh for time = 0 Time = 0 Mesh stats points: 16966 internal points: 0 faces: 33082 internal faces: 16118 cells: 8200 boundary patches: 10 point zones: 0 face zones: 0 cell zones: 0 Overall number of cells of each type: hexahedra: 8200 prisms: 0 wedges: 0 pyramids: 0 tet wedges: 0 tetrahedra: 0 polyhedra: 0 Checking topology...

End Can any one explain what it means and my mesh is OK or what ? Can I proceed further with this mesh or what ? Thank you in advance !! With regards, Gitesh |
Your mesh is fine. OpenFOAM is just complaining about 22 high aspect ratio cells. I believe OpenFOAM thinks any cell with an aspect ratio over 100 is too high, but this isn't an issue, it's more of a warning.

Thank you for your quick reply :)
So, you mean I can continue with this mesh file ? With regards, Gitesh |
Hi Gitesh,
I agree with Travis. Your mesh fine. You can continue with it. Regards, Toni |
