Detailed Description

An analysis for reporting the joint reaction loads from a model.

For a given joint, the reaction load is calculated as the forces and moments required to constrain the body motions to satisfy the joint as if the joint did not exist. The reaction load acts at the joint center (mobilizer frame) of both the parent and child bodies and either force can be reported and expressed in the either the child, parent or ground frames. The default behavior is the the force on the child expressed in the ground frame.
