• Local is a setting for the Coordinates option that causes results to be returned relative to the local coordinate system of a body.
• The alternative to the Local setting is Global.

Load the Modeler3D package and define a simple model.
Here is the angular velocity of the link body in global and local coordinates. Note that the expressions differ only slightly.
Here are the loads applied to the link body in global and local coordinates. Note that the expression for the moment in local coordinates agrees with our knowledge that the moment is applied in the local Z direction with a magnitude of 1.0.
The loads can also be expressed in the modeling coordinate system which, in this case, means that the moment is expressed in Euler parameters space.
