There are a couple of things to consider here.Â
- If you don't resolve the roughness with VERY small cells you won't actually capture the roughness.Â
- Most CAD kernals don't work too well at the micron level. Scaling may avoid the issue, but you'd need to scale in the "up" direction and then hope the mesh wasn't too skewed when rescaling in the solver.Â
Why do you need to resolve the roughness, but at the same time don't want to spend the cell count to actually resolve the roughness?Â
