Rough walls cannot be used together with the following model combinations:
• an -equation model with enhanced wall treatment or the Menter-Lechner near-wall
treatment
Note that the following are the relevant -equation models:
– all of the - models (that is, standard, RNG, and realizable)
– the Reynolds stress model with the Linear Pressure-Strain model selected
– the detached eddy simulation (DES) model with the Realizable k-epsilon option selected
• the Reynolds stress model with the Stress-Omega or Stress-BSL model selected
