Large eddy simulation (LES) turbulence

Large eddy simulation (LES) turbulence

OpenFOAM is distributed with a huge library of LES models as listed below.

As with the rest of the library, adding new LES models is straightforward; the new models are available for selection at run-time in the same way as others provided with the library.
