Problem description

Model:

Isotropic mass  
M 100.0
Anisotropic mass  
Mx 100.0
My 200.0
Mz 300.0
Rotary inertia  
I11 100.0
I22 200.0
I33 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)

General:

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

Results and discussion

The calculated reactions are in agreement with the applied loads.
