Difference between contact pair and identify pair

Please login with a confirmed email address before reporting spam

I am a little confused about the difference between contact pair and identity pair when I do some simulatation of solid machanics . And are there any restrictions of the study type? When we do stationary study, what is the difference between assembly with identity pairs and union? Thanks very much!
