Problem with specifying first element size in 2D Mesh

Hi

I'm trying to model turbulent flow in an axis symetric pipe using fluent. This requires high control of the first node from the wall (y ~10^-4). For the time being I have accomplished this using sizing with bias on the edges (in Ansys Meshing). When using this approach, I do not feel I'm in control of the first node, regardless of choosing element size or numbers of divisions.

I would like to specify first node size and a growth factor, is there a way to do that?

I have included an example mesh below.

Regards
Sigmund
