Hello, I have a problem and couldn’t find anything useful.

The problem is this:

1. There are 157 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 saw that you recommended using “Connected Parts (Karamba3D)” or "Eigen Modes (Karamba3D), but it seems like I have only one branch on my list.
