Wall Roughness Error

April 23, 2007, 12:42

Hi all..

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?

Thanks

probably because you are using a K-espilon turbulence model with Enhanced Wall Treatment. use Standard Wall Function
