Hello

I am trying to understand how the moment of inertia about the principal axes XX, YY and ZZ were calculated in the wing motion example of openFOAM.

The snippet of the dict file is :

mass 22.9;
centreOfMass (0.4974612746 -0.01671895744 0.125);
momentOfInertia (1.958864357 3.920839234 2.057121362);
orientation
(
0.9953705935 0.09611129781 0
-0.09611129781 0.9953705935 0
0 0 1
);

Thank you
