DDES length scale

I'm running a DDES-Spalart-Allmaras simulation in FLUENT and I'd like to visualize the demarcartion of RANS and LES regions.
How does it works the scalar "DES length scale" in FLUENT?
In my results, it's always > 0, and according to theory (FLUENT manual), negative value demark RANS region, positive LES region.
But I'm sure in my simulation it's NOT only LES because of the grid! Can someones explain me how does it work the scalar in Fluent?

Hello, I am using DDES-SST K-w and I want to visualize the demarcartion of RANS and LES regions. How can I find it? Where is DES length scale in Fluent?
