cmh is on a distinguished road

I am working on a problem where i need to add surface roughness in laminar flow scenerio.

Can I use the piso foam solver with the Ras type , set the filter to be laminar flow and still define surface roughness using he wall function. Is this correct?

Is there any other way to simulate surface roughness in laminar flow?
