User-defined
User-defined tire model is used to apply input contact patch forces/moments onto the tire hub
The User-defined tire model, unlike the Linear, Fiala, Calspan and Pacejka tire models, allows the forces generated at the contact patch to be defined externally and passed to the model as inputs. The signal input ports on the component represent the user-specified forces and moments along and about the ISO unit vectors.
For more information, see the diagram below and the Standard Tire help page.
Note: The  port of the User-defined tire component must be connected directly to the  port on a tire body component, as shown in the diagram below.
