看着篇文章:Nevertheless, it should be stressed that from a physical point of view, one should aim at a 3D LES with 2D LES being but a compromise imposed by computer limitations.
See "15.5.5. Advection Scheme for Turbulence Equations"
Irrespective of the Advection Scheme setting, the advection scheme for the turbulence model equations depends on the Turbulence Numerics option: ...
Note that Turbulence Numerics option also specifies the transient scheme for the turbulence model equations (see Turbulence Numerics in the CFX-Pre User's Guide). This can be overridden in CFX-Pre in the Solver Control details view on the Equation Class Settings tab.
