Help: about the enhanced wall treatment
 

hi,I am using Fluent to model the impinging jet with roughened wall.

I want to use the enhanced wall treatment, but I found there is no roughness option in the BC defininiton panel when I selcet the enhanced wall treatment. So I want to ask if Fluent provides the roughness option when using the enhanced wall treatment. or it needs an additional license to get it work.

Anybody has this kind of experience? Please help!! Thanks a lot!!

Best Regards!
