Element consisting of a frame (frame_b) that is fixed in the world frame at a given position defined by parameter vector r (vector from origin of world frame to frame_b, resolved in the world frame).
By default, this component is visualized by a cylinder connecting the world frame and frame_b of this components, as shown in the figure below. Note, that the visualized world frame on the left side and Fixed.frame_b on the right side are not part of the component animation and that the animation may be switched off via parameter animation = false.
