Default Assigning Wall Roughness in STAR-CD

Posts: n/a
Hi ,

I am trying to assign roughness to no slip wall. I could see that there are three constants A , B and C which has by default values of 8.5, 0 and 1 respectively. Then user has to input efective wall roughness(y0) and displancement(D). I went through Manual. Then I did calculate thickness of laminar sublayer. The roughness I want to include corresponds to completely rough wall. My question is that while assigning copletely rough wall, shall I have to just input efective wall roughness (y0) and have to keep everything else (A,B,C and D) as it is ? is this correct what I understood from Manual and reference for wall roughness. Thanks in advance. Thank you for your time and consideration.
