I'm not quite sure what the 'Behavior' property of remote points actually means. From what I understand, the remote point (pilot node) is connected to the scoped nodes via rigid line elements which have to retain their length. So 'rigid' behavior would imply that these line elements can only move and rotate as one rigid body. In 'deformable' mode relative translatory movements of the line elements would still be locked (since they would cause a change of length), but individual rotations of the line elements would be possible. Is that correct?

Hi,

I did watch that already, but it does not exactly explain how deformable behavior is handled by the solver. As far as I understand, 'rigid' basically creates a rigid body connecting the scoped nodes and the remote node, but how does 'deformable' work? If the scoped nodes can all move independently, how is the connection to the remote point established?

Hi,

Did you watch the video at the following time frame (5:04)? An example is presented where the pilot node (at the center of the hole) is connected to all the nodes at the inner face of the hole. Using this example rigid and deformable behavior have been explained. Also, please see if the following link helps you:

Yes, I did. Rigid seems like "all nodes move as one", but how exactly are forces and displacements exchanged between scoped nodes and pilot node in deformable mode?
