Options🔗

• Dynamic k equation
• Smagorinsky
• Wall Adapting Local Eddy-viscosity (WALE)
• k equation

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
