Hello, 

I am running a CFD analysis in 3DEXPERIENCE using the Fluid Scenario Creation App. Although I have precisely defined the surface roughness and created the FE mesh with the required fineness, the surface roughness is not being considered in the simulation. Here is the corresponding entry in the log file and the setup in 3DX:

 W A L L  B O U N D A R Y  C O N D I T I O N S
  =============================================

  Surface ID   Amplitude   Magnitude   User  Variables
  ==========  ==========  ===========  ====  ==================
           7          -1           0    No   Stationary No-slip Wall
 

Thanks for any advice. BR
