Has anyone ever used MD.ADAMS multibody dynamics software? My university doesn't have access to the knowledge base and the help file is kind of confusing. Does any one have any good sites that have tutorials? What I am using it in a biomech class, and have to develop a simple full body humaniod model (I know theres commerical models out there already, but this is part of the project). Particularly, I am having trouble trying to define the range of motion for joints. I want to model the knee, so I want to assign the joint to have a pre-defined range of motion.
