Hi, I have a steel structure model where I cannot do a Modal analysis, I think it's because I have an instability (see attached image), but I don't know how solve this one, if someone can help me, I will be very grateful, thanks.  Any doubt about my model I'll respond quickly. 

Pd. Sorry for my bad English, Im learning 😛

Hi @ANGELG552 

There are too many releases in the model. Model can be calculated when (for instance ) all "Pinned-Fixed" releases are removed

Thanks Krzysztof, I'll verify my releases, I don't understand where I should use it (releases) and it give me this type of problem or instability. 

Thank you!
