Class CustomAerodynamicProperties

java.lang.Object
  fr.cnes.genopus.nonWidget.vehicle.CustomAerodynamicProperties

public class CustomAerodynamicProperties
extends Object

This class defines an aerodynamic property to be applyied to aerodynamic parts of a vehicle (PATRIUS assembly). It has a dual nature, actually it is either an AeroGlobalProperty or an AeroSphereProperty depending on the constructor used.
