Creation of BL from extrusion of surface mesh

1

Hello,
I am trying to create a BL from a surface mesh. it works more or less correct with some ‘bumps’ in the nodes where different surfaces intersect.
for the creation of the BL I am doing the following steps:

  1. create a surface mesh
  2. use extrusion/ select extrusion by normal
  3. select all the faces from the surface mesh and change the distance to a negative value and number of steps
    also here is the surface:
