Dynamic Analysis of Circuit board assembl

[gimmejava]

I'm looking at doing a dynamic analysis (Random Environment) on a simple circuit board assembly using Pro/Mechanica. Based on your experience, what is the best way to model the interface between the part and board. I really don't care about getting into individual solder joints, but just to show a connection between the two. Does Mechanica automatically assume a weld between surfaces that touch? If so, this should be fine. See example below and thanks for your input. -Randall

gimmejava,


Per my experience with Pro/Mech if you have 2 objects that are resting or close to each other it treats them like one entity.

Thanks Krow, that is what I thought. So, if I want them to react differenly, I should provide an offset, then create a different type of constraint? I appreciate your response.

gimmejava,

As far as I know, you don't really have to provide an offset per se.
You just use the interface definition between the two bodies you need.
