Error message: instability in various nodes

Hi everyone, we’re fairly new to using RStab and RFEM. I’m uploading a project for you to take a look at. Most of the nodes display an error message: “Free to move in the ... direction.” Unfortunately, we haven’t been able to find a solution to this. Thank you in advance.

Best regards,

Hi tozi_fh,

A little tip: The shape of the unstable model looks like this, and you should bear in mind in RSTAB that members are only connected if they split the member:

Thank you for the helpful assistance! Quick question: how do I set this up so that it looks similar to yours, especially the colors? In my case, only the deformations are displayed, so to speak.
