Hi, I'm confused regarding the choice of mesh metric that can be used to check the mesh quality?? which metric can give a good representation of mesh quality, is it the skewness or orthogonal? I read some comments provided by the ANSYS community and they mentioned that the min. orthogonal greater than 0.1 will be acceptable. For me, I deal with CFD Fluent and I need to know:

1) which mesh metric I can use skewness or orthogonal?

3) To which value should I look for checking the quality, (the Min., Max., or Avg.) values of these metrics (i.e. skewness and orthogonal)?

2) what is the range of skewness and orthogonal to be defined as (accepted/good/ very good) quality?

For Fluent the min orthogonal quality should be above 0.1 to proceed to solver. If it is less than 0.1 then please improve the mesh. 
First check the locations of the bad elements. Please see following video for the same. 

Please go through help manual for more details

Looks like the Forum gremlins are out to play again, /forum/forums/topic/what-is-the-good-mesh-quality-skewness-orthogonal/  so I'll close this thread.
