Using Moco to Calculate Orthosis Actuator Force for Load Compensation

Hi, I have added an additional weight to a model, which is supposed to represent an orthosis. This orthosis should now provide just enough support to compensate for the additional load it has caused. Can I use Moco to calculate the required force and force progression of the additional actuator (ort...

CMC SetUp

Hi,
I would like to run the CMC tool on my personal model. What is the easiest way to create the tracking tasks?
Thanks in advance

Recalculation of muscle forces

Hi, I have recorded a sit to stand movement with the help of OpenCap. This worked without any further problems. I have now integrated an additional actuator into my model, which is supposed to be an active knee orthosis. Now I would like to recalculate the muscle forces. However, I am missing the Se...

Influence of a new body to kinematics

Hello, I have created a new body and added it to model2392. It should only represent a weight that you put on the model's leg. I would like to investigate how this affects the muscle forces etc. My code runs, but I get the following error message: [error] Mesh C:\Users\Annika\Documents\OpenSim\4.4\M...

Sit to Stand Motion

Hello everyone, I would like to investigate the sit-to-stand procedure with orthosis using the gait2392 model. However, I have not found any movement data or a motion file. Is it possible to download a suitable file somewhere? One of my ideas was to turn it into an optimisation problem and solve it ...

MATLAB, Python, C++ or GUI

Hi everyone,
I'm new to OpenSim and want to add an active knee orthosis to an OpenSim default model. I have no Python, MATLAB, or C++ experience. Which interface do you recommend? What are the pros and cons? Which interface is beginner-friendly?
I really appreciate any help you can provide
