Prescribed kinematics in forward dynamics

Hi All,
I was wondering if I can apply a prescribed trajectory to a link during a forward dynamics simulation?
What I am trying to do, is to give muscle excitation patterns and pelvis trajectory as INPUTS to my forward dynamic simulation.
Thanks,
Sina

Hi Sina,

You can prescribe coordinates in a model as a function of time, you can follow the steps in this forum thread

For a model with muscles, you'll need to specify excitation patterns as well to run forward simulation.

Please let us know if you run into problems using this approach.

Best regards,
