我正在学习网格质量评估相关的知识，想要以fluent的数值为标准，自己写一个网格质量评估程序，但是对于质量较差的单元，计算正交质量等角偏斜等体积偏斜时会完全无法对应，猜测可能是对于畸形单元的质心、面心、面法向、最大最小角计算与fluent的处理有偏差，阅读了fluent手册发现这些参数没有详细的计算方法或特殊处理，请问有什么可以参考的资料或代码吗？

I'm learning about mesh quality assessment and want to write my own mesh quality assessment program using Fluent's numerical values ​​as a standard. 
However, for poor-quality elements, the calculation of orthogonal mass, angular skewness, and volumetric skewness is completely inaccurate.
 I suspect there might be a discrepancy between Fluent's handling of the centroid, face center, face normal, and maximum/minimum angles for 
distorted elements. I've read the Fluent manual but found no detailed calculation methods or special handling for these parameters. 
Are there any reference materials or code I can use?

There are some notes in the Meshing course, and also mesh quality metrics in the Fluent course. However, other than User documentation I have no other information. Given the metrics are designed for Fluent, and calculated using schemes in Fluent I'm fairly confident they're correct.

是我的计算不够准确，不是fluent错误，我想知道fluent的详细做法，有具体课程的链接吗，感谢

My calculations were inaccurate, not a Fluent error. I'd like to know the detailed Fluent instructions. Do you have a link to a specific course? Thank you.

I teach the "full" course and am not as familiar with public video content.
