About 6 weeks ago, some one asked how they could get an LES code. They were advised as follows:

In Response To: how can i get some LES code? (danney)

Navier Stokes solvers for laminar flows are good basis for LES codes. You just have to add a routine for computing the SGS viscosity (Smagorinsky model).

Now, I don't understand this. Does one not need to make the code unsteady? Is the N-S Solver for laminar flow already unsteady?

Thanks.

Hi.

You need to have a unsteady NS solver for laminar flow, then you can ammend that code to add the Smagorinbsky model.
