CoordinateCouplerConstraint in ID and SO

Post by Roger Mathys » Wed Oct 20, 2010 5:25 am

Hi

I am using a neck model, where the movement of the lowest vertebrae (C7) is given as the generalized coordinate (pitch, roll, yaw) and the the movements of the upper vertebrae's are given as CoordinateCouplerConstraints relativ to generalized coordinate.

Doing ID and SO, I get strange result. e.g. the pitchmoment stays ~zero over the entire motion.

Does anybody have experience with CoordinateCouplerConstraints in ID and Static Optimization?

Where can I find more information about CoordinateCouplerConstraints? There is almost nothing in the documentation.

Please help,

Roger
