Usage

LES is selected by setting the simulationType entry

simulationType  LES;

LES
{
    \\ Model input parameters
}

Suitable for:

• 3-D cases, not appropriate for reduced-dimension cases
• transient, not appropriate for steady state

Initialisation

Typically initialised from a precursor calculation, e.g. employing RAS modelling.

LES Deltas

• Cube-root volume
• Van Driest

Wall modelling

• guide-turbulence-les-wall-modelling
