I am trying to expand the Simscape Vehicle with 4-Speed Transmission example to compare time-to-speed of vehicles with and without rear wings. I have attached a screenshot of the vehicle body subsystem below. Within this subsystem, I cannot figure out a way to add an external force function input representing the downforce and drag forces generated from the wing as vehicle speed increases because the lines that I think I want to connect the force input to are conserving (?) lines going to and from conserving ports. The red circle indicates where I think I would like to add in my forces generated by the wing. I would assume the downforce generated acts on the driven tires, thus increasing my normal load and available traction. I still need to figure out where I would add in the drag effects from the wing. I would like to see how the wing affects TTS performance.
Is there a way for me to add this function to the existing model or do I need to generate my own? Would it be wiser to try to recreate the model in Simulink rather than Simscape?
