Hello everyone,

I am trying to design a steel container, but my model is unstable. Can you tell me what might be causing this?

Best regards

Hello Clemens,

it was a numerical problem. Due to the shortening of the supports, the bracing failed, so I assigned a minimal compressive force to the tension members. After that, the calculation ran through :)

Thanks for the link to your FAQ... that helped me a lot.

Best regards
