Hi everyone

I a using openfoam for my internship. I need to modelize a spillway with valves and narrowing.
I have completed the blockMesh file and added some refinements in snappyHexMesh.


However I still have instabilities after some time of computation.
I don't know why I have instabilities but when I look the checkMesh I have : "Failed 1 mesh checks"
And I have 9 skewfaces in the sets file.

Do you know if skewfaces could be the reason of my instability?
Do you know How can I delete them ?

I achieved to reduce them (from 24 to 9) by increase the surfacelayer to 2. But I still have 9 skewfaces.


Thank you for your help.
