[Is Me Sharipu]

I wonder how to make a field function about Ksgs/Kres+Ksgs in STAR-CCM+2306, it is important to know the ratio below 0.2 according to pope.But there is no Ksgs function in DES, and TKE function means the Kres+Ksgs right?

I try to switch to LES, there is a Ksgs function, but no values in TKE function, so I still can't finish my work. Anyone knows how to make a field function to check mesh quailty in post scene?
