I've been playing arround with robot for a school project, trying to analyse a simplified structural model I've made of the Downland gridshell building located in Sussex.
I'm getting instabillity warnings, and useless results when I press calculate, and being a beginner I've struggled to figure out what the problem might be.
Changing the releases and supports, didn't do anything, so I'm running out of good ideas. I hope some of you guys may be able to help?
Kind regards, Jacob
Solved! Go to Solution.
Caused by releases.
You have applied releases to all bars making all of them truss bars so the whole model is unstable.
Correct or remove releases.
