Partially interfering mesh with 'no penetration contact', what will happen?

[321GO]

On my part there are certain notches on it's circumference that have an initial interference. As such the mesh is also interfering at those locations. The contact condition is set as 'no penetration'.
Now, will the solver even see this initial overlap? How is this handled if at all?

Or can such a conditions only be solved with 'shrink fit' type contacts?

If I understand correctly if there are no elements between the nodes on the two intersecting parts then they won't exert any force on each other.

In Ansys, it the initial penetration is smaller than the pinball, it will see it and enforce the contact

Greg / Rick, Thank you.
In Solidworks Cosmos there is an option shrink fit.
Does anyone have experience with this?

Would this simply inforce connecting elements regardless the distance betweem the meshes?
