FAS Multigrid in turbulent flow
 

does anyone know in applying FAS multigrid in turbulent flow with RANS model (esp. SST K-Omega), what consideration should be taken into account? I means when FAS multigrid is applied in laminar flow what changes in multigrid should be applied for expecting that multigrid work effectively in turbulent flow?
if anyone has experience or knows a good references, I'd really appreciate it if introduces me?

thanks in advance
