Discovery Refine Mode – Defining number of boundary layers

Currently, there is no option to specify the number of boundary layers to be generated. But, they can be controlled to some extent using the fidelity slider. At the low end of the Fidelity slider, three boundary layers are specified, at the high end of the slider seven layers, and in the middle of the slider five.

If you combine a local fidelity adjustment setting with the fidelity slider, you will get mesh as shown above.
