Hello everybody
I wanted to do a simple modal to see how the upper deck behaves compared to the lower one. between the two there are 6 FR4 bushings.
the lower bench is supported by 3 bipods, wedged on the lower interfaces.
on both sides there are two distributed masses.
i don't understand what simsolid's answer means.
is there a guide on errors?
Thank youimage

    Hi Cristian,

    Is the model shareable?

    The issue may be caused by regular connections. Are there any large gaps between parts that have been connected using regular connections?
