Static Optimization with weld constraint failing
Posted: Wed Nov 29, 2017 4:14 am
Hello !
This is my first project in Opensim and I am trying to monitor muscle activation of leg muscles during a squat.
I am using gait2392 model and making the motion file(.mot) from a motion captured in experiments.
I don't have the capability to measure ground reaction forces, so I am trying to weld the feet to ground,but every single static optimization which I run with weld constraints fail.
When I run the simulation without weld constraints , it manages to get me a solution ,but I know that is wrong.
I am using reserve actuators in both cases.
Do you have any suggestions?
Thank you!
