mesh quality
 

is good this mesh quality?

Best Regards

Orthogonal quality isn't the only reasonable criterion for a mesh. Also it depends on what you want to do. Post a picture of your setup and give some information about it and what you use for meshing!

Thank to your reply
you can see that here:

Orthogonal quality of 0.4 isn't bad per se. Do you face convergence difficulties, or why are you asking?

Thanks
I asked you Because I encountered to wrong answers.

Can you elaborate on this a bit? Post some relevant pictures...

I am doing free surface simulation of stirred tank. My answers are wrong in compare with the paper. I delet all cas&dat file because I knew they were wrong and I have not any pictures, now

Thanks in advance

Then I don't see how anyone can help here... hopefully, I am wrong.
