Vibrational Node Location Modal Analysis

[Anonymous]

Hi everyone, this is my first post an I'm excited to use Inventor. I'm just getting the hang of things so I don't know if this is the right place to ask or if it's a silly question.

I was doing a Modal Analysis of a solid I made, looking for it's natural frequencies as a free-free object. The first 6 modes had a frequency of 0, which is not surprising since it's free-free, but I got hits for the 7-10th mode. The frequencies line up and the animation is working, but the report mentions nothing as to the location of the nodes or anti-nodes of the vibration.

I can't find where to locate this. If anyone can help me with how to do this, that would be amazing,

Thank you

Hi! I suggest you add a Frictionless constraint on a face. Modal analysis on a totally free body may be hard to understand, since it is very rare to have such condition.

Many thanks!
