Mechanical Simulation’s CarSim 2020.1 introduces a new front suspension type called the virtual steering axis. This suspension type is intended to model passenger car independent front suspensions which have a split upper or lower control arm, meaning no fixed kingpin geometry. Rather than separate suspension and steering kinematics input tables, the virtual steering axis uses common 2D tables of jounce and steering rack travel to locate the wheel. This video shows this modelling approach used in CarSim for this suspension type
