Problem description


Isotropic mass
$M$	100.0
Anisotropic mass
$M_{x}$	100.0
$M_{y}$	200.0
$M_{z}$	300.0
Rotary inertia
$I_{11}$	100.0
$I_{22}$	200.0
$I_{33}$	300.0
Centrifugal axis of rotation	(0, 0, 1) through (0, 0, 0)
Gravity load vector	(0, 1, 0)
Rotary acceleration axis	(0, 0, 1) through (0, 0, 0)

The ROTARYI element and anisotropic MASS element are also tested with local coordinate systems and with finite rotation.

The calculated reactions are in agreement with the applied loads.
