When trying to apply a moment generated by damping at a joint using a bushing force, should I specify a damping ratio or an angular damping coefficient. If it is a damping coefficient, should the units be in radians, degrees or cycles?

Thank you,

When trying to use c3d2trc.m, in the MatlabOpensimPipelineTools, the m-file loadc3file.m is needed, this file did not seem to come with the download. Should this file have been included in the zip file, or is this a file which I need to provide?

Thank you,

I am trying to use a bushing force to model the stiffness/damping of a thin film placed across the front of the patella. Intuitively, I had assumed flexing the knee (moving in the -z direction) should cause the spring to generate a positive moment in the z direction which should result in an increas...
