Roughness for K-Omega Turbulence models

Hi,
We want to use K-omega based turbulence model for flow over terrain by using Roughness and checked the previous messages in forum. But we are not able to edit in CCL as mentioned in previous messages in forum with an error message "it is not physically valid". Please Can any body suggest if we went wrong, r else is there any other way to input roughness for K-omega based models in CFX. Thanks, Ratnam. |

I've set surface roughness with no problem in CCL for the SST (K-omega based) model. This only works in 5.7.1 (I believe).
Also, look at the CCL for roughness on a k-epsilon case to make sure you have the syntax correct. The options are case sensitive. Jeff |
