instability 3 floor mesh

[ByrnePM]

Hi,

I am having an issue with an instability type 3 problem on the nodes of my mesh on my composite floor ?

I have attached model below ? 

Can anyone see where the issue is coming from?

Thanks,

Has anyone had a chance to look at this ?

Try to block RX in the definitions of releases (this will remove the instability warning). Then calculate  the model and check MX values for bars with releases and add RX releases (or partial RX release) where needed.
