This model is stable in the sense that odd modes do not grow,
the ellipsoidal figure nicely holds together throughout the simulation.
The gradual decay of the m=2 mode is due to the small violation of continuity
equation. |

| This model is stable in the sense that
no indication of growth of odd modes. The amplitudes of
all the modes remain to be roughly constant. |

| This model is moderately unstable. The ellipsoidal configuration
holds together for quite a long time, but from the mode analysis,
we found that odd modes grow slowly. |

| This model is unstable to the elliptical strain instability.
The bar-like structure is suddenly destroyed between t=4-7 dynamical times.
Odd modes grow rapidly from the beginning and surpass m=2 mode quickly. |
