Hello, 
I am using Automatic contact surface to surface to model the contact between two objects in LSDYNA. the first one is a horizontal mat with prescribed three components earthquake. The second object is a cylinder overlying this mat. Under the input motion,the mat starts moving and the cylinder starts moving and may have an uplift. Is there a way to check the contact any type of results to know if there is a total uplift (separation) between the two objects meaning that no contact points between both objects. 

 

Thanks
