Follower
A follower is defined through a point that follows the cam boundaries or edges with certain optional offset. The following options are supported to define a follower point:
•
Centroid of selected entities (domains, boundaries, edges, or points)
•
Geometric point (single point)
The follower point can be a part of rigid or elastic bodies. In case there is a requirement of multiple points to follow the cam boundaries or edges, multiple instances of this feature should be used.
