Based on the doxygen documentation ( https://simtk.org/api_docs/opensim/api_docs/classOpenSim_1_1ConditionalPathPoint.html#a5fbccc632d996235419c0313a8fa369b ), the ConditionalPathPoint::connectSocket_coordinate() method would be called by passing in a reference to the coordinate, something like this...

it is very strange that a lot of much more complicated models work fine with CMC I don't think it is so common to run CMC with a contact mesh and elastic foundation force. If it's possible for your application, you might try simplifying the problem by using a joint (or constraint) on the floor inst...

I want to simulate a system with changing forces over time depending on location and velocity If the forces are functions of time where the functions are known before the simulation begins, you could try using some other type of Function (expand the "Inheritance diagram for OpenSim::Function" at th...

You are correct: RRA should not be run over time intervals where GRFs were applied to the left foot in the experiment but were not measured.

Muscle activations are unitless and forces are expressed in newtons. Some additional information about the muscle models can be found on the "Muscle Model Theory and Publications" section of the documentation and the associated publications ( https://opensimconfluence.atlassian.net/wiki/spaces/OpenS...

Could you please advise if updating OpenSim will affect my existing files and data? OpenSim will not search your hard drive and modify files. However, model files are automatically updated to the newest version when you open them, so if you open a model and then save it without changing the filenam...

The inputs and outputs of the Inverse Dynamics Tool are described on the "Getting Started with Inverse Dynamics" page in the User's Guide ( https://opensimconfluence.atlassian.net/wiki/spaces/OpenSim/pages/53090063/Getting+Started+with+Inverse+Dynamics ). General information about OpenSim workflows ...

The line "state = model.initSystem()" immediately after the "for" loop is creating a fresh underlying computational system and assigning it to the variable "state" in Matlab, so anything that was done to the "state" variable before that line will be lost. Please try removing that line.

I would like to know how to gain full body center of mass and joint power. I used Analysis Tool but it didn't work. These are both Outputs: - OpenSim::Model::com_position ( https://simtk.org/api_docs/opensim/api_docs/classOpenSim_1_1Model.html#a44d8bd8fb7b2aa45c118c06cfabfadb8 ) - OpenSim::Joint::p...

The "Overview of OpenSim Workflows" page in the documentation (https://simtk-confluence.stanford.edu:8 ... +Workflows) provides a brief description of the OpenSim Tools.
