Dear Opensim community, I am working with a colleague on the scapulothoracic model (Seth et al., 2019) and we would like to automatize the computation of muscle moment arms (MMA) over time for several motion trials. We use the MATLAB API. To do that, we would like to wrote a for loop that set the mo...

Hello, We are using the same model and we have the same issue with the static optimization (problem with acceleration constraint violation "ground_thorax_rot_x") . We used residual actuators too (on all degrees of freedom of the ground thorax joint, and with very very high values (50000 N) to be sur...

Thanks for the explanation and the suggestion, I will try this!

Alicia

Dear all, I am using the Thoracoscapular model (Seth et al. 2019) and I would like to change the thoracic ellipsoid radii (the highlighted line in the attached .osim file screenshot). The aim is to carry out a kind of sensitivity analysis, so I want to automatize the process through Python API. Thor...

Thank you so much for the advice, now it works perfectly!

Hello, Sorry for reopening this old topic, but I am trying to change muscle insertion with Python and it does not work. In fact, the code above proposed by jimmy does in theory exactly what I want but when I run a similar code, I got an error for the last line with the setLocation function. Attribut...
