checkMesh : Mesh non orthogonality
Can someone explain me what is mesh non orthogonality ? Maybe with a picture?
Because I have this information in checkmesh and this is giving me troubles.
Thanks for your help.
Hello, did you get any answer to your question?
I have now finished my thesis and have therefore not touched OpenFoam in a while.
From what I remember, non orthogonality is not simple mathematically speaking. It's in fact the angle difference between two adjacent cells.
In my case, I looked at this problem with my advisor because I thought I had very high non orthogonality figures. After looking at the mesh, nothing was wrong so we wondered if there was not a slight problem in the way OpenFoam is computing this value ...
Now, take my word with caution since I don't remember exactly what my problem was neither the answer I received from my advisor.
Sorry not being able to help you more.
