Designating the Contact and Target Sides Properly - Lesson 1 

Contact is often utilized in engineering simulations to allow various components to interact with one another. The contact definition has a distinction between the Contact side and the Target side. This video focuses on the proper designation of the Contact and Target sides in order to achieve proper behavior and numerical accuracy. It provides various examples to demonstrate the designation of Contact and Target sides when parts with different mesh sizes, different geometries or different material stiffnesses encounter one another.
