Should I remove Coordinate Limit Forces for Static Optimisation?
Posted: Mon Jul 12, 2021 6:13 am
Hello everybody,
I would like to use the "Upper Extremity Dynamic Model" (https://simtk.org/projects/upexdyn) with the Static Optimization algorithm to calculate Joint Reaction Forces (using Joint Reaction Analysis).
However, as I understand, there are Coordinate Limit Forces (CLFs) present in the musculoskeletal model. These are used to enforce the limits when using a forward dynamic simulation like CMC (right?).
As I want to use Static Optimization instead of CMC, I should be able to simply remove the CLFs from the model and get proper muscle forces, as well as JRFs.
Could you confirm this assumption?
- A big thank you in advance!
(Let me know if you need more input!)
PS: Also, the CLFs would make the calculated JRFs obsolete, as OpenSim would "include their contribution as part of the resultant joint load" (https://simtk-confluence.stanford.edu/d ... s+Analysis). Is this correct as well?
