Wall Roughness Error
I just saw the FLUENT help file that we can change the roughness parameters in FLUENT, by selecting boundary conditions > Wall>Momentum >then can select the roughness parameters.
But how come when i go to the momentum tab, there is no roughness parameters for me to change? only options available are wall motion and shear condition.
Any ideas please?
Re: Wall Roughness Error
probably because you are using a K-espilon turbulence model with Enhanced Wall Treatment. use Standard Wall Function
