RE: Plugin

<t>Hi Daniel,<br/> <br/> I've encountered the same problem that Ayman is referring to. Luckily, if you can wait it out for the release of 1.9 in the near future you won't have to worry about building JointReactions anymore. This newer JointReactions will also have added functionality.<br/> <br/> - M...

RE: Contact Forces

<t>Hi,<br/> <br/> I'm not sure what you are trying to do, but if you are looking for something that implements a contact model, JointReaction is not the answer. If you are looking for a tool to calculate the reaction loads at joints then the JointReaction analysis is exactly what you need. It is now...

RRA crashing problems

<t>Hi all,<br/> <br/> I'm trying to complete RRA and CMC on a jumping trial and keep getting the error below at the beginning or RRA.<br/> <br/> "ERROR - Evaluating GCVSpline at 0.008327 outside its domain [-0.185833, 0]"<br/> <br/> This occurs just after "Padded kineticsStore to start time of 0.064...

RE: Project: EMG driven model

As I recall, the method described in this paper required a pretty extensive set of calibration protocols on a dynamometer. Would we have the resources to do similar measurements?
