If you choose the RSM, the following submodels are available:
 Linear pressurestrain model (Section
12.7.4)
 Quadratic pressurestrain model (Section
12.19.13)
 LowRe StressOmega (Section
12.19.14)
Figure 12.16.1: The
Viscous Model Panel Displaying the Reynolds Stress Model Options

The following Reynoldsstress options are available:
 wall boundary conditions for the Reynolds stresses from the
equation (Section
12.19.12) for the linear and quadratic pressurestrain models
 wall reflection effects on Reynolds stresses (Section
12.19.11) for the linear pressurestrain model
Other options that are available based on your case setup include:
 viscous heating (always activated for the densitybased solvers) (Section
12.19.1)
 inclusion of buoyancy effects on
(Section
12.4.5)
For the Reynolds stress model, the following nearwall treatments are available (Section
12.10):
 standard wall functions
 nonequilibrium wall functions
 enhanced wall treatment
If wall boundary conditions for the Reynolds stresses from the
equation and/or wall reflection effects on Reynolds stresses are/is selected, then all the above nearwall treatments are available for selection.
If you choose the enhanced wall treatment, the following options are available:
 pressure gradient effects (Section
12.19.9)
 thermal effects (Section
12.19.10)
If the quadratic pressurestrain model is selected, then you can set either the standard wall functions
or the nonequilibrium wall functions.
If
LowRe StressOmega is selected, you cannot select any nearwall treatments. You do have the option of selecting any or all of the following
options:
 transitional flows (Section
12.19.7)
 shear flow corrections (Section
12.19.8)
