Instability Type 2 in RZ

[Anonymous]

Hi,

I have just built a structural steel model, loaded vertically and laterally and am experiencing type 2 instabilities in RZ in an illogical pattern. Is there any advice as to how to fix these?

I have attached a screen shot for information.

Thanks in advance.
