Thanks Sherm, I have implemented a bushing force (for three rotational degrees of freedom) into my simple model (two cylinders with a joint and the bushing force in between, one of it the "ground"). And my Opensim2.4.0 did not complain on loading the model (?). For upgrade I only found an Opensim v ...

Hi, I would like to implement kind of backdrawing forces/angular momenta in a free joint (on the way to a multisegment simulation of an elastic body, e.g. a stick or later a human tibia). Best would be, if it would be possible to define a kind of potential for every coordinate. Is that possible or h...

Can you please help a beginner: Is there any example showing the usage of the joint reaction tool? How to specify the settings properly? Isn't it possible to do a joint reaction analysis on the base of inverse dynamics results e.g of your standard gait model? My first trial crashed the entire Opensi...
