If you choose the LES model, the following subgridscale submodels are available (Section
12.19.15):
 SmagorinskyLilly
 WALE
 KineticEnergy Transport
Figure 12.18.1: The
Viscous Model Panel Displaying the Large Eddy Simulation Model Options

The LES options that are available for the SmagorinskyLilly are
 Dynamic Stress
 Dynamic Energy Flux (available only when the Dynamic Stress Model is enabled)
 Dynamic Scalar Flux
The LES option that is available when the KineticEnergy Transport submodel is selected is the
Dynamic Energy Flux Model.
It is also possible to modify the
Model Constants, but this is not
necessary for most applications. See Sections
12.3 through
12.9 for details about these constants. Note that
C1PS and
C2PS are the constants
and
in the linear pressurestrain
approximation of Equations
12.75 and
12.76, and
C1'PS
and
C2'PS are the constants
and
in
Equation
12.77.
C1SSGPS,
C1'SSGPS,
C2SSGPS,
C3SSGPS,
C3'SSGPS,
C4SSGPS, and
C5SSGPS are the
constants
