non-orthogonal mesh
 

Hello,everyone!
In OpenFOAM, when we use non-orthogonal meshes,we should do someting to make sure the computational accuracy is ok. As far as I can see,there are two ways we could pay attention to :

1.Set the "nNonOrthogonalcorrecters" in the fvslution. (for example 20)

2.Set the "corrected" or "limited" schemes in the fvschemes.(for example Guass linear corrected)

I have a question that what else I can do to ensure accuracy of calculation except the two ways above when using non-orthogonal meshes.
Thank you very much!
