Great. Thanks Nick. We do use the setOutputIndex() function to select the desired index of the vector to use for the foot position. We appreciate your insight and look forward to a future version that allows inclusion of dynamic stretching of the reference desired trajectory to match the current tim...

Hi, We have two questions that we hope someone can help us with: Q.1. We want to track the trajectory of a particular body segment (such as the toes) with MocoOutputTrackingGoal. We defined the output path for the body as: "FootGoal->setOutputPath("/bodyset/ltoes|position");". Is this the correct wa...

I have a problem that started since OpenSim 4.2 and up to the current 4.4. I defined a muscle controller function and created a dll file as a plugin for it. In these versions of OpenSim, the GUI will only load the model files containing this controller if I add the file to a 'plugin' folder and put ...

Has anyone succeeded in building a Windows Visual Studio API application (C++) with OpenSim static libraries only? I have tried this in several ways with no success. I will appreciate any insight on how to do this if at all it is possible.

Thank you very much for that guidance. It works; after I have cleaned out my previous API installation and made a fresh installation with a more recent version. Apparently I must have been mixing versions of the API and GUI installations. Thank you.

Great, Thanks Ayman. I will get to that version and see how this works.

I have two questions about IMUPlacer: 1. Is it possible to place virtual IMUs on a model? By this I mean specify an IMU at a given location and orientation on a given segment so it's output would simulate that of a real IMU when the segment moves? I want to study the impact of IMU placement and orie...

Thank you very much Ayman. I checked in Help->XML Browser and my MuscleController was not listed. But just to make sure, I also copied the two example folders 'AnalysisPluginExample' and 'BodyDragExample' to my desktop without changing a thing except adding a 'build' folder to each. I then created t...

I am having problem developing a plugin for OpenSim 4.2 to enable me open a model that has a newly defined muscle controller. I see that OpenSim 4.2 GUI was built using Visual Studio 16 2019-MSVC on Windows-x64. I created a folder with my MuscleController.cpp and MuscleController.h files containing ...

Hi, I am running a simulation by integrating the model equations in OpenSim C++ API. I set the initial and final times; but the integrator threw an exception about being unable to proceed beyond the final time. Below is the simulation output in the command window: Loaded model StanceModel from file ...
