Quality checking - intersections

Hello All,

I have a small question regarding Hypercrash. I am checking the intersections and penetrations in my model using the Quality menu – check tree selection and I get intersections between each part. Intersections between two parts are highlighted. What does number below “Int.” correspond to? Is it the number of intersections between the two parts or the number of elements intersecting? I also checked the model using “check all solver contact interfaces” under quality menu and I get a different result. Even though there are many elements intersecting between two parts in two different regions, it is being listed as only one intersection. I don’t seem to understand the difference between these two ways of checking the model intersections. Could you please provide me some light on understanding the difference between these two ways of checking the intersections in the model?
