Roughness for K-Omega Turbulence models -- CFD Online Discussion Forums

July 1, 2005, 05:30	Roughness for K-Omega Turbulence models	#1
ratnam Guest Posts: n/a	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.
