Robot instability type 1

[mete.akyuzTWC3Q]

Hi, I’m a beginner with Robot structural. At this time I have a model with a lot of errors named instability type 1. I tried several things to fix this error but couldn’t find any solution. I tried to change my bars and nodes for example, bu this didn’t worked aswell. Could somebody help me with my school assignment please..?

and is it possible to import my model in this forum?

Hi @mete.akyuzTWC3Q 

Instability type 1 is reported model is not stable (its parts can move or nodes can rotate)

Check model displacement (graphically and in displacement table). then correct regions with too big displacement.

If model geometry is defined correctly, instabilities can be caused by too many releases defined for model bars.

Remove releases and check if instabilities are reported.
