Trouble with Roughness Height
I'm a relatively new user of STAR-CCM+ V4 and wish to simulate the roughness height within the atmospheric boundary layer. The goal is to create homogeneity of the velocity/TKE profiles as best as possible. Unfortunately, the node for "roughness height" as stated in the manual does not show up even though the wall surface specification is set as "rough". Strangely, the Wall Roughness Parameters node does appear. What may be the problem?
Donwload the new version 4.02.011. This issue was fixed.
