I am trying to develop Hexa mesh in a flow domain with a scour hole around the bottom of the cylinder. The flow domain is shown in the figure.

The cylinder and the bottom surface are treated as walls, so an inflation layer must be provided around them.

To provide the inflation layer to the bottom surface with scour hole, first layer thickness, growth rate and the number of layers are provided to the edges 1,2,3,4, 10,11,12 and 13 (as shown in the blocking figure). But the edge properties provided to the edges 1,2,3,4 are getting copied to all the parallel edges (edges 5,6,7,8,9 and the edges in the same row). It leads to the development of inflation layers above the bottom surface in the scour hole region (as shown in the attached figure).

I need the inflation layer only to the bottom surface in the scour hole region but not above it.
Please suggest possible solutions to this problem.
