I was looking at contact geometries and found an example of a ContactMesh at http://simtk-confluence.stanford.edu:8080/display/OpenSim/OpenSim+Models#OpenSimModels-ContactGeometry <ContactMesh name="block"> <body_name> block </body_name> <location> 0 0 0 </location> <orientation> 0 0 0 </orientation...

I've been looking at constraint sets and when I was looking at different ways to write a constraint set, I found two different examples seen below: <ConstraintSet> <objects> <CoordinateCouplerConstraint name="sternoclavicular_r2_con"> <isDisabled> false </isDisabled> <dependent_coordinate_name> ster...

Hello,

I'm looking at ContactGeometrySets. I don't know the difference between ContactHalfSpace and ContactSphere and how they work. Would someone be able to explain the difference between the two?

I've been working with muscle points (Moving, Via, and Fixed) and to see how they work, I modified the Tug_of_War.osim model so that the block drops and is able to make contact with the floor. First, I placed the box in the "air" with simple point to point muscles without any extra points in the mid...

When looking through some of the models that come with OpenSim, I noticed that there are different types of muscle that can be define (ex. Schutte1993Muscle, Delp1990Muscle, Millard2012EquilibriumMuscle, and Thelen2003Muscle). How do these types of muscles differ and in what circumstances are each o...

I've been messing around with ellipsoid wrapping algorithms in order to understand how they work. I've been specifically working with the Tug of War model that's already included with OpenSim and been trying to add my own ellipsoid wrapping algorithms. In this simulation, I edited the model so that ...

Hey all!

I'm having issues understanding the different wrapping algorithms (Hybrid, Midpoint, and Axial). Would anybody be willing to explain to me the difference between them and how to implement to implement them within a model?

Regards,

Hello! I'm somewhat new to OpenSim and was looking through the code for the arm26.osim model. Within the model under many of the muscles, there are spots where a PathWrapSet is defined. Under the PathWrapSet there's a PathWrap and under there is a <range> . Here is some code from the arm26.osim code...
