pressure on the surface

[NikonF6]

I have a conical disk 250 mm dia.
On its conical surface is circ-segment 220 deg r124 and r118 (like a belt pressure on the shieve)
The segment is above the cone on the dist 0.1 mm

When I apply normap pressure (2D or 3D) the pressure appears as normal pressure at all surfaces of the segment (even at sides 0.1 thick)

I did a try to apply pressure after and befor meshing
I applied pressure before meshing and looks fine, pressure is only on the segment large area, but after meshing it appear all around again the sigment.

How i can exclude pressure at thin sides of the segment?

Thanks a lot for your time

i am using NX 7.5

0.1 sides, have you got your small feature tolerance set right ?

 

[NikonF6]

mesh size = 2 mm global
feature tolerance set as 3% (Fiel - New - Sim - (now run meshing) then small feature tolerance 3%)
(as i undestand this all features smaller than Mesh*0.03 will be made as separate feature mesh)
Did not help
But if I inscrease that segment thickness from 0.05 to 0.25 mm all is fine. I would not like to use it because the stiffness increses.
