Hi Arthur, Wonderful to hear from you, and thanks for reporting. If you're able to build the OpenSim API then you can enable python bindings by turning on a flag (BUILD_PYTHON_WRAPPING in CMake) and that will locate/try-to-find other needed tools (e.g. swig) and the python available on the build mac...

Hello, Removing the muscles form the model should be easy though it involves editing the xml file of the model (.osim). You just remove the xml blocks for the corresponding muscles (typically these have the full class names rather than just "Muscle" e.g. "Millard2012EquilibriumMuscle"). If you have ...

Hello, Thanks for reporting but it's not clear where the script you're referring to comes from. If it's published by us we'll need to fix and incorporate into our testing suite. If however this is your custom code, we'll need to find out what changed, and when and if we confirm the API has changed, ...

Hello, Looking at the code/line where the exception occurs, it seems to be a corner case where the wrapping algorithm reports that a wrapping has occurred but also reports no actual wrap points. It's an internal inconsistency between the core libraries and the application/GUI that we need to account...

Hi Ekaterina, If you have the application installed, you can go to the help->Report a bug option, just make sure to describe the environment you're using and include any model/data/minimal code files necessary to reproduce. If you're on github you can open a new issue on the repository https://githu...

Hi Ekaterina, Thanks for reporting, looking at the change log nothing stands out as potential reason for this change of behavior other than possibly using a different python version/environment. Please open an issue and provide a description of your environment (Python distribution/version, IDE if a...

Hi David, Thanks for reporting. Let me start by clarifying that, as it stands, OpenSim (Outside of Moco) is single threaded, as such the fact that the server has multiple cores or threads would have no bearing on performance. Running the same version of OpenSim/conda package would factor out differe...

Hi Daniel, The tricky part about Mac OSX platform is that there are two different architectures (intel based x86_64 and arm64 for M1/M2). We have not published M1 based distribution as of now, so you'll need to use the x86_64 (and Rosetta) of Matlab in order to use OpenSim in Matlab up to and includ...

Hi Stephan, Generally speaking, code has to be integrated into the opensim-core codebase in order to be available for both python and Matlab bindings. In which case you'd need to make a PR into our opensim-core that becomes part of OpenSim. Alternatively, and possible faster way to go is to write py...

Hi Dennis, The messages reported by conda suggest that you require a python 3.12 (due to some other package in your environment pin-1), while there's a variety of options to install opensim with earlier python versions. I'd suggest you create a fresh conda environment with python 3.8 or 3.9 and inst...
