Initial Contact Compression on Thin Walls with Single Element through the Thickness

[srwopschall]

I have a block impacting a thin walled cylinder with a single element through the thickness. At time t=0, there are nonzero contact forces with clear marking of the domain boundaries. I believe this is because the opposite faces of the thin elements are being detected as 'in contact'. The auto contact penetration scale should catch this and avoid marking those faces as candidates, but this does not appear to be happening.
