Re: Contact Forces and Contact Geometry

Omar - There are a few models included in the OpenSim distribution that have contact geometry defined. You can take a look at the "BouncingBlock" model and the "ToyDropLandingModel" to see how contact is defined. Please let us know after looking at these models if you have remaining questions. Best ...

Re: Implementation of CMC using MATLAB API

Maya -

You should use the call:

cmcTool.setExternalLoadsFileName([residualMotorsFilePath residualMotors]);

See the CMCTool doxygen for other calls:

Re: Implementation of CMC using MATLAB API

Maya - As Ajay noted in his email, you can open the setup (XML) files in any editor (Notepad++ will color code for you) and take a look at the settings. Compare the file generated by your Matlab scripts (the tool should have a print command or similar). Please verify that the files and paths are cor...

Re: Drop Landing Model

Jiang - You can see an example of how to specify contact in the BouncingBlock model that we distribute with OpenSim. The drop landing model was intended as a demonstration model only. It's representation of foot-floor contact has not been validated in a research setting (e.g. the placement of the co...

Re: Human's whole body model

Jiang - There isn't a model like this that I know of. You might be able to combine a neck model with another full body model. I'm curious about how you plan to use the model. What structures or motions are you most interested in and what questions about those structures or motions do you hope to ans...

Re: How to create muscle defect?

Roman - Thanks for your interest in OpenSim. Please see my responses below: 1) How can I create muscle defect? I need simulate defects of muscles after resection soft tissue tumor. You could change the max isometric force of a muscle to simulate a reduction in strength. This is one possibility - the...
