Thanks, I have been so frustrated trying to find meshes that supported that method. I was about to give up 😌

With regard to points 1-4, it sounds like once I have accomplished these points on a single mesh (no multi-mesh independence study required 😄) , that I will have a mesh which should provide meaningful CFD results that would compare to experimental results +/- 1 % or so, is that correct?

This does make sense to me and it has some relevance for a different layering issue [I am having here](https://www.simscale.com/forum/t/layering-for-yplus-of-less-than-1/83022/12).

You have given me renewed hope that I can eventually obtain good enough CFD results to aid me in designing my new aircraft 😄.

I will implement your suggestions on a new mesh and report back 🙂

Thanks so much,  
Dale
