Hi Dimitar,

Thank you very much for the response. But unfortunately none of the links actually have an example of building a CustomJoint with Python API. Would be helpful if you know of any. Thanks

Hello Everyone,

I am struggling with setting up a CustomJoint using Python API. Could any one point me to a simple example for doing the same? Thanks

Hey Cui Weilling,

Open the model in opensim -> Tools -> Plot -> Y-Quantity -> Moment arm -> muscles (Choose the ones you want) -> X-Quantity(Joint angle against which you want the moment arm to be computed with. Typically the joints over which the muscle acts.) -> Add.

Good Luck,

Hi Everyone, I am trying to use the Python API in order to generate some plots of my models in static conditions. Plots such as force-length curves, muscle moment arms versus joint angles and more. I see that this is doable with the Matlab API using functions such as getForceLength. But I am unable ...

Dear Dimitar Stanev, Thank you for the reply. But unfortunately I am unable the properties using python API. Please find below the small code small I am trying to execute. Your help is much appreciated. I need to change the dimensions of ellipsoid wrapping and not for cylinders. import opensim as os...

Hello, I am trying use the python API to generate an ellipsoid wrapping. What method/function should I use to change/set the dimensions of the ellipsoid using the python API. Looking the WrapEllipsoid class I do not see a way to access any attributes to change the dimensions of the ellipsoid functio...

I agree with your that Simbody is indeed a powerful physics simulator. But making Opensim agnostic to the physics would have made it even more powerful. Now I am forced to switch between different physics simulators as I cannot integrate all into one.

Hey Christopher Dembia, Thanks for your reply. Having such a tight integration with Simbody makes the usage of OpenSim a bit restrictive. I am using a physics simulator called Webots which based on ODE. It would have have been really nice to be able to Integrate OpenSim with physics simulator of our...

Hello everyone,

I was planning to use openSim with another physics engine. Is it possible to use Opensim without Simbody without having to go through a lot code change to OpenSim. Looking forward to your responses
