LES simulation for flow over aerfoil

      I want to simulate the flow over aerofoil using LES incompressible flow simuation. I want to ask what is the best solution strategy for LES simulation?


      what is the best solver for solving pressure and velocity equation? PISO or Fractional step method (FSM)?


      what is the correct adjustemt for interative time advancement solver (PISO) and the non-iterative one (FSM)?


      The spatial discretization i used:



      is there any documents for recommeded setting for LES?

      There is a best practice on the Customer Portal, your supervisor may have access: as a student you won't.

      is there a tutorial for LES simulation for aerofoil?


      what is the tutorial name?

      There are tutorials on aerofoils and tutorials (in the Turbulence training) on LES. There is a best practice on the Customer Portal.

      I checked FLUENT tutorials but all of them for RANS models, I did not find any tutorials about LES.


      I did not find best practice on the customer portal.are you sure ?

      Yes. Look after Scale Resolving Simulation.
