What kind of contact should I put here? ANSYS
I want to run a modal analysis on an assembly. The image attached is a simplified version of it. The "mount" attaches to the plate via bolts (red) and is threaded (blue) onto the mount. What kind of contact should I put at the interface (yellow).

Hi,

Modal analysis only supports the linear contacts. It this particular cases bonded contact seems to be good choice among all the linear contacts.

Hello, Thank you. 
While doing other analysis like random vibration, quasi static, static structural, and thermal can I add a frictional contact (coeff: 0.2) between the two surfaces (SS 304 (bottom) to aluminum 6061 t6 (top mount)) and a beam element that connects the two components? Modelling bolt and adding pretention is expensive and it's affects need-not be studied in this case. We need to study only the behaviour of the mount and the plate under loads. Please help.

 It’s amazing how these choices affect overall performance!
