Hi,All Regarding (topology of the multibody system, mass and inertia properties, hardpoint locations, characteristics of springs and dampers, characteristics of hydraulic actuators, transmission and engine parameters, etc., etc.), for these data: I can modify the 3D model’s structure for the topology of the multibody system based on publicly available vehicle information. Can the other data be assumed/defined or found from public sources? Is it possible to produce a demo, and then seek channels to obtain a rigorous dataset to support it?
