Cosmos - Single Node Vibration

Discussion created by Guest on May 26, 2006
Hi all,

I am trying to run a frequency analysis on an assembly of about 30-40 parts, 6 solids, the rest shells. The results I keep getting are individual nodes within a shell vibrating at 60,000 Hz or something ridiculous like that. I am expecting the entire assembly to give me some sort of arch shape at more like50-100Hz.

Attached is an image of what I'm talking about. Any idea what I'm doing wrong? Thanks,
