Contact Set vs Global Bonding

Hi,

I have a 3 part assembly and the global contact is set to bonded. I'm running a frequency analysis to find the natural frequencies.

Can I assume since the parts are touching that they will be bonded or do I have to define a contact set?

I ran both simulations with these results:
Just global:
Mode No. Frequency(Hertz)
1 122.65
2 138.95
3 279.87
4 387.1
5 846.1

with contact set:

Mode No. Frequency(Hertz)
1 -1.7596
2 -0.10258
3 -0.028497
4 -0.0098229
5 0.055411
6 0.70618
7 997.02
8 1101.8
9 2860.8

Thanks for any tips.

Lee
