Output Hunt-Crossley contact forces

Post by Margarida Machado » Fri Nov 12, 2010 11:48 am

Hi,

I want to evaluate the knee contact forces using different contact force models.
Therefore, firstly I modeled the knee contact forces as elastic foundation forces.
To output these forces, I ran a force reporter, which gave me information about passive muscles forces and contact forces.
After that, I did the same using the Hunt-Crossley model.
However, at the force report, I only got the passive forces. Why this happens? Is there any other way to output the contact forces using the Hunt-Crossley force model?

Thanks for all help.

Hi Margarida,
I was trying to implement "elastic foundation model" to model the foot-ground contact. But I do not know how should I do that. Should I make some changes to my .osim file? If yes, what are those changes?
It would be great if you could help me to do that.
Regards,
Sina
