Model driven by kinetics

Thanks for your suggestions troubleshooting. I have been looking into
why my model, when driven by kinetics, appears to be so unsymmetrical.
I stopped driving the model by kinetics data and strictly applied a
constant moment to the model, and I am posting the following Left and
Right GH Joint Reactions. It appears as if there is a problem within
my model, however I still have yet to figure it out. There appears to
be a spike in the GH forces halfway throughout the push.

Any suggestions as to why?

I appreciate the help,
Thanks again,
Sarah

Hi Sarah

I have taken a look at the model.

Here is a few things:

You say that you drive the model using a constant moment, in the environment
file a force and moment is applied, does this force corresponds to the constant
moment?

Try to increase the RecruitmentLpPenalty in the main file this will normally
smooth out such peaks that you have on the reactions. Please read more about the
penalty in the reference manual.

In the jointsanddrivers.any file you have reactions on the sc and wrist drivers
is this by purpose?, there are muscles in the model to taken up these reactions.

Best regards
