MoCoInverse : Objective Function not Converging

[Sivaprasad Kunnath]

Hello Nicholas,

Thank you for your help. Following the instructions, I was able to get consistent result in activation. The activation values when analysed, followed the expected behavior. However, the muscle forces that accompanies the activation values, are distorted. It seems to be oscillating between 0 and 1 for all muscles.

This type of oscillatory pattern is consistent for all dominant muscle groups. The muscle force sets are bounded between 0.1 to 1, and we are using DeGroote Muscle with added damping. I am curious to know whey the muscle forces are saturated at 1?

Thanks for your constant support.

Regards,
Siva

Hi Siva,

Those look like the muscle excitations, not the muscle forces. Muscle force should be proportional to activation (if passive force is excluded).

How are you computing "Force Normalized"?

Best,
Nick
