Dear All,

Good day!

I am trying to perform a Frequency Analysis for simple model. In that, I tried to use a spring connector with selection of two faces and I got some natural Frequencies.

Second case for same model , I tried to use a spring connector using point selection. In that I am getting a different values for Frequencies. 

Can you help to explain differentiate between these two options and when to select face selection and when to select Point selection for spring connectors.  

Thanks & Regards,
