Forward simulation problem ?

Submitted by daotient on Wed, 08/19/2009 - 00:59

Hi everybody,

I have a problem in my forward simulation, if you have a free time, thank you very much for your help.

The problem is happened during my forward simulation of gait analysis, once the tracker agent is created, the gait model is smoothing over the ground during the foward simulation. Note also that the joint histories are well etablished. I wonder the problem is related to translational parameters of tracker agent or translational tranning parameters but I don't know how to set up these parameters or there are maybe other solutions for this problem ? 

Thanks one more time for your help if possible

Hi Dao,

Could you explain the behavior you are seeing a bit more? I'm not sure quite what your model is doing, but sounds like you may want to try increasing the stiffness and damping on the tracker agent, and see if the model more closely is able to follow the inverse simulation results.  This is probably most easily done by just deleting out the current tracker agent (Motion> Delete and use the Delete Tracking Agent button) and then creating a new one with increased stiffness and damping.

Hope this helps!
