How do you evaluate your mesh quality?
 

Hello, i am working hard on understand the meshing process, and one thing that is not clear so far is how to check the mesh quality, so far i just check the minimum orthogonal value and the maximum skewness value, and try to optimize this values using a fine mesh smooth transition and such (all the sizing options).

My question to you is:
-What parameters do you use to have a reference of whats your mesh quality?
-What values do you modify to improve the mesh quality?
