.ModelicaAdditions.MultiBody.Parts.InertialSystem

Information

An instance of this class defines a coordinate system: the inertial
frame. All parameter vectors and tensors (e.g. position vectors)
are given in the home position of the multibody system with respect
to the inertial frame.

One instance of class  InertialSystem  MUST always be present for every
multibody model.

In order to identify the desired axes of the used inertial frame in
the icon, the labels of the two axes can be defined as string parameters.
