I have an issue that I cannot visualize in my grasshopper model. I performed a Solver for Formfinding a Pavilion, and when wanting to perform a Karamba Analysis, I have issues with the deformation and results in general. The main problem are the deformation and that the analysis has the message
“1. There are 660 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.”

Hi, you have set all elements as trusses, meaning that you structure is kinematic. You should either set them as beams, or triangulate the entire structure.
