Hi All,

I have a 3D blade/airfoil mesh that has a fine looking prism boundary along the front 80% of the blade, but the prism layer hits a point where it just starts shrinking to almost nothing...

The blade technically has 4 surface patches along the chord, one for the leading 10%, bottom, top, and an internal baffle surface coming off the trailing edge (to maintain the sharp edge and keep prisms growing out into the fluid).

When I was using wall functions (and therefore my first prism layer cell height corresponded to ~ 200 > y+ > 30) the prism layer was fine, but now that I am asking icem for a much lower first layer height (~ y+ = 5), I'm getting this behavior.

Has anyone seen this before? Does anyone know which settings might be causing this and how I could get a constant height prism layer all the way out to the end of the baffle?

Thanks!!
