Karamba - rigid body modes

Hi,
I seem to have this problem regarding the supports? I have tried to fix it with no good anwser.

  1. There are 8 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, your geometry is not internalised so I cannot see anything in the script.

Hi, this is the rhino file that goes with the gh

Hi, your elements are not split at their intersections. The Connected parts component shows multiple branches meaning that parts are not connected together.
