Hi
Can someone tell me how to do an LES computation from RANS simulation ? Or should I run the LES Simulation from scratch ?

Becasue I heard from other people that its always good to do a RANS and then restart the simulation with LES . Or to initialize the LES simulation with a RANS result. If its the way then hows it possible in StarCCM+ ?

Run the RANS and then just switch to LES. Or am I misunderstanding something?
