Overlay additional nonsolid objects

Hello Guys,
In the Comsol Manual there is this statement:
"You can also overlay additional nonsolid objects on top of solid objects to control the distribution of the mesh and to improve postprocessing capabilities. For example, add a curve object to a geometry to control the element size along a 3D curve or add a point to guarantee a mesh vertex in a specific location."
But, as far as I know, there is clear explanation on how to do that.
My problem is the following: I have a 2D geometry in which I solve a fluid problem with a convection-diffusion-reaction problem, since it is strongly convection dominated I need to have a good control of my mesh. In doing that I need to add another curve on a already present Bezier curve - the Bezier curve represents the geometry, the other curve will control the mesh distribution at the wall. How do I do that? Any hints?
Thanks for your time,
Cheers,
J
