### 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:

- `First Order`

  The Upwind advection scheme is used.

- `High Resolution`

  The High Resolution advection scheme is used.

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.
