Singular Stiffness Matrix Error - Karamba

Hello All, 

I have already been looking through previous comments and attempted some of the suggestions proposed there, I have made sure that my points are flattened and I have divided the lines into smaller segments for beam recognition. I have a grid, with 5 support points and I am trying to run an analysis on this structure. The Singular Stiffness Matrix Error keeps popping up. I would really appreciate any help at all on this matter.

Many thanks,

Helen.

Hello Helen,

in your model there were disconnected elements. In Karamba elements are joined only when their end-points meet. 

Best,

Clemens

Thank you so very much Clements! I really appreciate this. The little note really helped me understand the issue. 

Helen.
