Hi all,

I'm doing a simulation of the impact of the injury of certain muscles on the increased burden on other muscles during a motion task. I want to modify the roof of muscle activation (from default 1.0 to a lower level), but I think that there is only an entry for <minimum_activation> from the OpenSim Class Reference. Is there a way to add constrains to the maximum activation for certain muscles in the .osim file (from 1 to 0.8 for example)? Is it possible to achieve that without modifying the maximum isometric force?

Thanks a lot!!!

You can do this using "control constraints"; there's some information in the "Control Constraints File" section of the "CMC Settings Files and XML Tag Definitions" page in the documentation: https://simtk-confluence.stanford.edu/d ... raintsFile

Thank you so much!
