Using simscape multibody - Is it possible to simulate the body motion without any external forces acting?
I am attempting to simulate the motion of a human arm. My goal is to determine the angular rates of the upper limb segments e.g. humerus relative to thorax.
Using 3D Rotation theory was proving difficult and I was hoping I could build a simulation and simply input the rotation matrices I had derived in my MATLAB program. I then intended to devise kinematic equations to compute approximate joint torques. The data I have used for this method is from 3D motion capture data in water - digitization of marker points in 3D space.
My simulation is very simple. Currently, Gravity is the only external force acting on the model.
No joint torques have been applied.

Hi Josh, This isn't exactly a human arm, but this blog post includes a set of examples and videos describing how to model a human walking using Simscape Multibody: Walking robot modeling and simulation with Simulink, Simscape, and Simscape Multibody. You may be able to gather some info from it.
Also, this previously answered question may also provide some insight : How to Accurately Model a Single Human Leg in SimScape.
