Right. There is rigid body motion.
So how do we give such boundary condtions:
Five nodes on a circle(2D), these five nodes can only move toward the center of circle--there is only radial displacement and no tangential displacement (no rotation). Suppose that we fix one node, how about other nodes? How to apply BCs?
