Can I use Large Eddy Simulation like steady?
 
By setting time iteration to thousands, and time step to only one?
Does it give correct results?

I am asking this because I can only see horseshoe vortexes at the leading edge of a protruding airfoil with LES. K-e and k-w do not show this vortexes.

Thanks.

I'm not completely sure what you're asking, but you wouldn't have the steady state solution, you would only have the solution at one timestep.

the thing is, I can not see the horseshoe vortex in front of a protruding object from the wall except LES method. I think RANS methods do not show horseshoe vortex. that's why I asked this question. I want to see the vortexes which are in big scales.
