Aero Drag

The aero drag allow you apply aerodynamic forces on vehicle body.

The parameter variable pvs_aero_drag is used to activate or deactivate aerodynamic forces on the body. Where, '0', '1' are mapped to Inactive and Active respectively. It is used to activate appropriate groups created for the aero drag. Inactive represents aerodynamic forces are not applied on the body and Active represents aero dynamic forces applied on the body.

When aero drag is Active, dependent variables pvs_aero_frontal_area, pvs_air_density, pvs_drag_coefficient are used for aero drag force calculation in the older aero force implementation.

An aerodynamics implementation (Adams 2019 onwards), doesn't need parameter variables such as pvs_aero_frontal_area, pvs_air_density and pvs_drag_coefficient. The output communicators of type variables automatically get created that refers to the value from the property file and communicates it to the MDI_SDI_TESTRIG.
