I’m a structural engineer and I am just starting to play around with Grasshopper and Karamba.
I am facing an issue with the Analyze component. I’m getting the following error message:
“1. There are 18 rigid body modes in the system. This means some parts can move freely without causing deformation.
Try to use the ‘Eigen Modes’-component and activate the display of local coordinate axes: The first eigen-mode will be the rigid body motion.
If this does not help, check whether you have a pinned support directly attached to a hinge. A hinge introduces an extra node which may cause the problem.
When analyzing a flat shell structure one has to lock the rotation perpendicular to the plate in at least one node.”
I have looked for a solution online but although finding many threads about this topic, none of the solutions have worked. I would really appreciate it if someone could have a look at the attached file and give me a hand.
