I am trying to perform LES simulation for high mach flow (0.9). I am using comsol 5.5 version. The problem is, default "Single Phase Terbulant LES" physics only perform simluation for mach flow < 0.3. Also "High Mach number flow" Physics have Rans k-w model and there is no LES terbulant model in it. LES Terbulant simulation for 0.9 mach number is possible in COMSOL multiphyics? if yes please let me know how?

Thanks in advance.

Same problem. I want to do a SST model. But it is not available with High Mach Number Module.

I wanted to know is it possible to make our own High Mach Number Module by adding Turbulence flow module and Heat transfer. I think it will solve all the same equations. Please correct me if I'm wrong.
