I have this error when I try to analyze the model.
I read some other topics with rigid body modes but I couldn’t understand how to deal with it in my file.

- There are 138 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.
Thanks in advance for your help ^^
