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 polyMesh for time = 0
Time = 0
internal points: 0
internal faces: 16118
boundary patches: 10
point zones: 0
face zones: 0

Boundary definition OK.
Point usage OK.
Upper triangular ordering OK.
Face vertices OK.
Number of regions: 1 (OK).

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 !!
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 ?
I agree with Travis. Your mesh fine. You can continue with it.
