Re: Conda OpenSim slow on Linux

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...

Re: No "osimJavaJNI" file on Mac OSX 14.5 / OpenSim 4.5

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...

Re: Example of plugin that implements a data reader for alternative IMU system

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...

Re: Conda Install failing

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...

Re: disarticulation of bones after scaling MOBL_ARMS_41

Hi Kristy, This likely is a visualization only problem that we fixed already in later versions of OpenSim. That problem was caused by losing track of the folder where the model came from so instead of the application using the MOBL_ARMS custom geometry folder it's using the stock geometry folder whi...

Re: showMotion()

Hello, There's a line in the header of sto (and mot) files that specifies whether the angles are in degrees or radians. Motion files are assumed to have rotational coordinates in degrees (inDegrees=yes) so you can set it to match the data in the file. For OpenSim use the .mot and .sto are interchang...

Re: Problem in openning model

Hello, This is a visualization only issue due to missing geometry/mesh files, it has no effect on modeling or simulation. If the model uses stock opensim mesh files it should work out of the box as is, otherwise the model authors should provide a set of mesh files in the same folder with the model (...

Re: Persistent Visualizer Issues

Hi Nathan, Please open an issue on github or file a bug report so we can dig deeper into the issues/differences between machines/environments that work and others that don't. Not sure if these issues are model specific but I'd try models with built in geometry rather than with mesh files (e.g. an ea...

Re: Failed loading dynamic libraries

Hello,

My recollection is that OSX version 11 has been retired by Apple, as such we build/distribute/support OSX version 12+. Please try another mac with a more recent OSX version and let us know if the problem is resolved.

All the best,
-Ayman

Re: Visualization with Simbody

Hi Giovanni, The pose of the model in visualization depends on the state/coordinate-values. Some models have coordinates that can be set to move them above/below ground. I think that's what you have, it's not necessarily a bug that a model appears below ground if that's the case. You can also hide t...
