Hi Dears

Is there any way to run a steady case with large eddy simulation turbulence model, ? Or better to ask is it possible?

Best regards...

Hi,

LES is inherently transient - you cannot run this in steady state.

Good luck!

It's possible and it exists and there are numerous implementations of it but I don't think you will find anyone that will still consider that LES: it's called a laminar model.

LES is inherently a time-accurate simulation by definition. If you arbitrarily run it in steady mode, you will end up with a laminar flow because the fluctuations about the mean must average to the mean.
