Thank you both, it worked perfectly after following the instructions at https://github.com/mitkof6/OpenSim_API_ ... tion_force and loading within python with

Hi, There's a Windows and a Mac build of the following plugin, but no Linux version ( https://simtk.org/frs/?group_id=986 sources here: https://github.com/opensim-org/ScapulothoracicJointPlugin ) Supposing the building it from source is straight forward (bonus point for anyone with a binary), where ...

Thank you very much, Thomas and Hide - everything seems to be working now

Thank you very much for this information, I did not think of the integrator's default tolerance. Just to confirm, does it mean that when I re-integrate, all the controls have been preserved by default (i.e. I am integrating from the last state of the last integration, and not from the beginning) ? m...

Hi, I am trying to perform a simulation step by step in python. The results differ between a 0.2s integration and two 0.1s integrations. Would you be able to tell me if there is something wrong in these few lines of code? I am using the build_simple_arm_model.py" example. The controller brain = osim...

I am struggling here as I am missing a few key pieces to make sense of all this. So the small forward integration goes like this : manager = osim.Manager(arm) state.setTime(0) manager.initialize(state) state = manager.integrate(0.1) And we can get the state of activation and excitation of the muscle...

Christopher, thank you very much for your answer. I will update this post as soon as possible

Hello, I am trying to create a custom controller in python, and I had no luck going through the forum so far. I have compiled opensim 4 with the python wrapper and the example file "build_simple_arm_model.py" runs fine, it uses a prescribed controller with a stepfunction on over 2 seconds that gadua...

It does seem to work, thank you! It still doesn't want to compile but I think that's because I am not including some libraries in the compilation. That's an other problem! /usr/bin/ld: /tmp/cco9ybJX.o: undefined reference to symbol '_ZNK5SimTK10Visualizer12drawFrameNowERKNS_5StateE' //usr/local/lib/...

Thank you very much for your answer.
I did try to pause the program after initSystem but it left me with the same white window.

I tried to compile your code but I got:
