Direct dynamic analysis

Hello,

I would like to know if it was possible to make direct dynamic analysis with anybody?

Thank you,

Best regards,

Hi Claude,

Would you please explain more about the meaning of ‘direct dynamic analysis’ in detail ?

Best regards,

I was wondering if I could make a model move with joint angle datas? Direct dyamic might not be the good term as there is no complete muscle data available.

Hi,

  1. If you want to do some kind of ‘forward dynamics’,
    then we would say that AnyBody can not do forward dynamics analysis in current version.

  2. If you can get all the kinematics data of human such as joint angles,
    then you can drive your model without no problem.

Hello,

Thank you for your response.
Would it be possible to run a model that used to be driven by C3D markers, with joints angles datas, or will I need a different one?

Can you explain how the software uses the joints angles datas to run a model?

Thank you in advance for your precious help,

Best regards,

Claude Pothrat

Hi Claude,

Please take a look at the tutorial ‘Making things move’, Lesson 1. You could start by modifying the FreePostureMove model in the Examples folder. You will notice that is uses AnyFunInterpol class to define interpolation functions for your joint angle data.

Let us know if something is unclear.

Kind regards,
Pavel
