Help with contact sets

Hello everybody, i've got 2 problems.
I made an model of a bicycle frame for my internship, using surfacemesh im trying to measure the displacement. I made the frame in 1part, and split the body into all the different pipes so i gotmorre than 1 body. This is to take the contact surface of the pipesin to account.

question 1: I used bonded contact sets to for the mesh, becauseonly the global contact : bonded did not cut it. Is this the rightway?
question2: Do i also have to bond the different surfaces on one ofthe seperate body's?

Problem 1: When i run i get the following message: Warning: ratioof clearance/ element size in at least one element is larger than1. Do you wish to continue
If i click yes it does calculate the outcome normally withoutproblems. How does this message effect the outcome?

Problem 2: If change the bondages only a little bit (like only inorder or something) the outcome changes by a few percent.

Im just trying to compare different models so the excact outcome isin no interest of me, only the relative outcome. making my methodrealy unreleable.

Long story short, does anyone have a awnser to one or more of thesequestions and problems?
