Inertia in Local System

Inertia in Local System

By default the inertia tensor is reported in the global axis system and about the CofG of the selected mass.

The tensor may also be expressed about the principle axes and the CofG by taking the 'Principal axes' option.

In the most general case it may be expressed about an arbitrary centre and in a local axis system defined by the user by selecting 'Centre user defined' and 'Local axes'.
