Let the analysis run through.  Check the deflected shape.  You will see it pretty quickly.

After calculations select nodal group $SUB...$

After I find the nods we should eliminate them?

You should look at the elements they belong to and check why they are separated from the rest of a model (assuming this is not intentional).

I check all the structure, and all is connected.

Now the error disapear but the deflection is bigger than expected.

I'm sorry but I neither know the assumptions you made to estimate the deflection (of a beam, slab, for static analysis, design module ? ) nor any knowledge of your model.

This is my model. Can you help me?

You have to check your model  especially where you have a not ortogonal Panel beam (number 25 )

Some bars are not connected to this panel and also the column panels are not conected to it (panel 25).

Hi

I am doing a structural analysis of an individual steel module which is used for modular building project. I modeled this module with all its elements (floor and ceiling joists, wall studs etc.), applied loads in Revit structure 2016 and exported it to Robot structure analysis for structural analysis purpose. But during the analysis, it gave me some warning as shown in attached pictures. I also attached the robot file. It is really appreciates if you can help me. I want to delete these warnings but I do not know what I should do. Thanks in advance

Please check post 11 from http://forums.autodesk.com/t5/robot-structural-analysis/instability-type-3/m-p/6475461

In addition please do not post the same issues in multiple topics on the forum as it may cause many people looking at the same problem separately rather than being able to see what others have already managed to find out. Thank you for your understanding.
