About Damping (something new)

Hi Everyone,
I started a discussion several days ago about the damping in Electromagnetic Anslysis. Now I just find something new! I used a very simple model(Just mechanic). A polymer bridge and a block of nickel on top of it. I apply 1N(-Z, point down) force uniformly on the nickel. Then I did transient analysis, the bridge (together with nickel block) started to shake then it stopped. It is so wired that I didn't set any energy loss.
That's a very simple model that I can have its static results which means it will stay still finally. So the Comsol is applying some damping factor even you didn't set?
Any one have any idea on that?
Thanks a lot!
