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