static optimization

Hi, I just wanted to check my understanding of a few things: 1) If you have a motion (e.g. an elbow flexing and extending) and you run inverse dynamics (ID) on it, you get the joint torques necessary to reproduce that motion 2) If you run static optimization on that same motion you get muscle activa...

Inverse Dynamics - Static optimization relationship

Hi, I'm struggling to understand the relationship between the output of the inverse dynamics tool and the problem that static optimization solves. My understanding is that inverse dynamics outputs the joint torques that would make a model follow a specified motion. Are these same torques the target ...

The command i'm using and the error message are shown below in the code tags. The first included folder is where simbody was installed to and ...
