surface roughness in FLOW-3D
 
Hello~

Did FLOW-3D use roughness height(m) to define surface roughness ?

Tkanks your help!!

Yes it is based on the measurement and in length/height (m) units.

ck5825, thanks your reply.

But, what is "in length/height (m) units"? I can't understand.

Andy it is referred to surface roughness measurement and SI unit used in Flow-3D is m.
