Soccer Component

Soccer Ball Model

The soccer ball model consists of three visualizer arrows that show the Magnus force, drag force, and velocity vector. The golf component also contains a Modelica Standard Library MultiBody bodyShape component, some visualizer components with different CAD shapes used in the animation, and Magnus and drag forces.

Above is the diagram view of the soccer ball component. The aerodynamic forces are calculated in the MagnusForce and DragForce components.
