Help ! 6 rigid body modes in the system

[yf_chen]

1. There are 6 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.
   how can i fix it? i cannot find the problem.
