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, length and color of the arrowcan vary dynamically by providing appropriate expressions in the inputfields of the parameter menu.
The quantity parameter defines what the vector represents, allowingtools to scale e.g. forces and torques differently in a consistent way.For the default value RelativePosition the obvious scaling is1 and the relative position is shown as is.
