Is there anyway, Simbody classes can be accessed and used in matlab using API?

Hello Everyone, Is there any way I can use SimBody classes like PathSpring, CablePath, ContactForce, etc. through its API along with OpenSim API in Matlab. For example, I would like to set a cable with PathSpring (using SimBody API) between arm and forearm of arm26 model(using OpenSim API). Is that ...

Hello all, I have to set excitation and activation to muscles in every loop of integration in matlab. This is done so that the metabolic probe attached to the model, can get this information from the muscles and calculate the metabolic cost. Activation is easily set into the muscles. But when I set ...

Hello, How to get metabolic cost from the model using OpenSim API commands. The procedure I followed : 1. Attach metabolic probe to the model in OpenSim GUI using the already given python code. 2. Import this model in Matlab. 3. From the saved files of joint trajectory (theta vs time), muscle activi...

Thankyou Ong for your reply.
Yes, I am able to do that in GUI. Sure, I'll take the help of API commands to convert that for matlab.

Hello, I created an actuator storage file using matlab scripting. I ultimately want control.xml file from this. For that, I used the python script in OpenSim GUI named createControlsFromStorage.py. This file basically created my actuator controls file which I can give as input to the actuator constr...

Hello, I am trying to import an the model of 'Thoracoscapular muscle contributions to shoulder movement and work' in OpenSim GUI and in matlab. This model, I got from this link https://simtk.org/projects/thoracoscapular. But I am getting the same error in importing it at either place. Error is somet...

Hi Mike, Regarding my code, I perhaps was using a wrong value of elbow torque, which was resulting in wrong output. Now using InverseDynamicsSolver of OpenSim API, the obtained value of shoulder and elbow torque is giving me almost the same muscle activation plot as that obtained from OpenSim withou...

Hi all, I do have a doubt regarding the timing in CMC results. When I see the inversedynamics.sto file of arm26 model, it starts at the time of 0 and steps 0.0083333 seconds forward in time. When I do static optimization, the time steps as well as start and end time exactly matches with that in inve...

Hi, Apologies for not giving the full information but the problem is solved now. The Arm26 model which I was using has muscles attached to it, which was creating the anomaly in joint torque calculation (probably because of the passive force which it was exerting). When I removed the muscles from the...
