Understanding kinematics analysis

Dear all,

I’m trying to understand the kinematics analysis. I built to this aim a simple model. Before the calculation, I thought the model was kinetically determinate (42 DOFs and 42 drivers, no joints), but the kinematic analysis always failed.

Please can anyone look at my model (see the attached file) and help me understanding what is wrong?

Thanks in advance for any help

Cheers

Arnaud
