adding external loads in opensim

Hello,
I am a beginner to this software.
I have a query- Can I add constant force in a static model and generate joint reaction forces as results?
If yes please specify the way?
Note- I also need to eliminate ground reaction force.

Thanks in advance.

Yes, you can apply forces to a model and compute reaction loads at joints. Not sure what you mean by "eliminate ground reaction force." You might start by consulting the following pages of the documentation:
- "Getting Started", https://simtk-confluence.stanford.edu/d ... ng+Started
- "Overview of OpenSim Workflows", https://simtk-confluence.stanford.edu/d ... +Workflows
- "Examples and Tutorials", https://simtk-confluence.stanford.edu/d ... +Tutorials

Thank you, sir for your response.
My query is I don't have any experimental data neither I need any motion in my musculoskeletal model.
A model is been kept static and no force is been applied not even ground reaction force.
Now, a constant external force is being applied, how the external force will get distributed in joints and muscles.
This is what I want to calculate. Is it possible to calculate using existing models and datasets?
If yes please specify the steps or any link I could follow.
It would be a great help.
Thanks.
