Warning after changing the metabolic probe to "integrate"

Hi All, When I change the probe operation of the gait2392 model to "integrate" and run the CMC tool, a warning raises saying "WARNING::metabolics: Sdot (glut_min2_l) = NaN!" for all the forces. And the process becomes so slow. I wonder what happens and how can I fix this problem? Thank you in advanc...

Can I use control signals to generate motion?

Hi All, What I am tring to do is: I used CMC to calculate the control signals for each muscle in unassisted walking condition. Then I added six torque actuators to L/R hip, knee, and ankle to simulate assisted walking condition and have my own control signals for these actuators. I want to find what...

Re: Where can I find the modified .osim file?

Hi Ayman,

Thank you so much for your reply!

I added this line of code and a new .osim file appears. But there is no torque actuator added to this new model. I wonder why is it the case?

Where can I find the modified .osim file?

Hi all, After I successfully run the .m file to add a torque actuator to the gait2354_simbody.osim file, where can I find the modified model and open it in OpenSim? I tried to open the original gait2354_simbody.file but the actuator doesn't exist. As a reference, the .m file is shown below: import o...

Difference between simulating the exoskeleton with torque/coordinate actuator

Hi All,

I found some projects using torque actuators to simulate the exoskeleton device while others are using coordinate actuators. I wonder what's the difference between using these two kinds of actuator?

Thank you,
