FixedArrow
Visualizing an arrow with dynamically varying size in frame_a
Library
Modelica/Mechanics/MultiBody/Visualizers
Description
Model FixedArrow defines an arrow that isshown at the location of its frame_a.
The direction of the arrow specified with vectorn is with respect to frame_a, i.e., the local frame to which thearrow component is attached. The direction and length of the arrow, its diameterand color can vary dynamically byproviding appropriate expressions in the input fields of theparameter menu.
