Modeling spring between two surfaces in COMSOL

Hi,

I am modeling a structure from silicone which has multiple holes in it as can be seen in the image. My question is, how do I model a spring with a predeformation between two sides of one hole. So I mean a spring modeled between the horizontal points of the hole which are blue in the image.

Hope to hear from anyone soon,
