I am simulating the shock wave/boundary layer interaction (SBLI) using SU2.
Everything is ok using SA, while grid-induced separation is observed in the case simulated by SA_EDDES. I guess that in SA_EDDES attached boundary layer is simulated by LES rather than RANS. Who can give me a suggestion for the usage of SA_EDDES in SBLI at Mach 2.9, or how lengthScale = wallDistance-f_d*max(0.0,(wallDistance-distDES)) can be writed as output for me to figure out where are RANS and LES.
