I confronted with a tough problem about contact pairs. I attached my model below. The upside is a structure, the downside is the other structure. Both has semi-sphere roughness, At the beginning, the two semi-sphere just contact, no penetrate. With a downward pressure on the upside structure, the upside has great vertical displacement, resulting the large penetration. However, the software didn't alarm any warning or error. I used the identity pair for this contact. What's the reason for that?
