Outlet Boundary Conditions for LES
I am doing LES of the flow around a bluff body using Fluent 6.2.16. I use velocity inlet BC at the inlet and pressure outlet BC at the outlet.
1. Are these BCs appropriate for LES?
2. I have gone over some of the literatures related to LES and found that Convective Boundary Condition (CBC) is used at the outlet in LES. Do I have to use CBC to get accurate results?
3. How to enable CBC in fluent 6.2.16 if available or incorporate it using User Defined function?
Thanks in adavance
