JointReaction,Integrator

How does the JointReaction analysis determine what accelerations are used ? There does not seem to be any method of inputting the accelerations for this analysis. Is there some interpolation or integration going on here? The XML example on the wiki implies integration.

Hi Jonathan,

There's no integration going on there, the analysis runs on a frame-by-frame basis. Since you provide forces, the analysis utilizes Simbody underneath to compute accelerations based on the multibody system.

The integration setting in the xml files are an artifact that's unrelated to JointReactions.

Hope this explains, and sorry for the confusion
